| # Mesh snip application | |
| ## Overview | |
| This app demonstrates the use of a Bluetooth® SIG Low Energy Mesh model as indicated by the name of the application. | |
| For Mesh topology information, see this [link](https://github.com/Infineon/CypressAcademy_BT101_Files/blob/master/PDFs/WBT101-07A-Mesh-Topology.pdf) | |
| For Mesh protocol details, see this [link](https://github.com/Infineon/CypressAcademy_BT101_Files/blob/master/PDFs/WBT101-07B-Mesh-Details.pdf) | |
| For Mesh application structure, see this [link](https://github.com/Infineon/CypressAcademy_BT101_Files/blob/master/PDFs/WBT101-07C-Mesh-Firmware.pdf) | |
| ## Instructions | |
| To demonstrate the app, follow these steps: | |
| 1. Build and download the application to the AIROC™ board. | |
| 2. Run the application and refer to the Mesh Client Control user guide. | |
| Refer to Bluetooth® SIG Mesh Specification: | |
| https://www.bluetooth.com/specifications/mesh-specifications | |
| ## Notes | |
| 1. All mesh apps use a common shared source library for common application framework functionality located at: mtb\_shared\wiced\_btsdk\dev-kit\libraries\btsdk-mesh\COMPONENT\_mesh\_app\_lib. This library may be edited as needed. For example, to change the PUART baud rate see mesh\_app\_hci\_init() function in mesh\_app\_hci.c | |
| 2. The default PUART baud rate is set in that location to 921600 | |
| 3. The application GATT database is located in mesh\_app\_lib as well, in file mesh\_app\_gatt.c. If you create a GATT database using Bluetooth® Configurator, update the GATT database in the location mentioned above. | |
| ## Application Settings | |
| Application specific settings are: | |
| - REMOTE\_PROVISION\_SRV | |
| - Enable device as a Remote Provisioning Server | |
| - LOW\_POWER\_NODE | |
| - Enable device as a Low Power Node | |
| - INCLUDE\_TIME\_AND\_SCHEDULER | |
| - Adds support for Time and Scheduler Server Models | |
| ## BTSTACK version | |
| BTSDK AIROC™ chips contain the embedded AIROC™ Bluetooth® stack, BTSTACK. Different chips use different versions of BTSTACK, so some assets may contain variant sets of files targeting the different versions in COMPONENT\_btstack\_vX (where X is the stack version). Applications automatically include the appropriate folder using the COMPONENTS make variable mechanism, and all BSPs declare which stack version should be used in the BSP .mk file, with a declaration such as:<br> | |
| > COMPONENTS+=btstack\_v1<br> | |
| or:<br> | |
| > COMPONENTS+=btstack\_v3 | |
| ## Common application settings | |
| Application settings below are common for all BTSDK applications and can be configured via the makefile of the application or passed in via the command line. | |
| ##### BT\_DEVICE\_ADDRESS | |
| > Set the BDA (Bluetooth® Device Address) for your device. The address is 6 bytes, for example, 20819A10FFEE. By default, the SDK will set a BDA for your device by combining the 7 hex digit device ID with the last 5 hex digits of the host PC MAC address. | |
| ##### UART | |
| > Set to the UART port you want to use to download the application. For example 'COM6' on Windows or '/dev/ttyWICED\_HCI\_UART0' on Linux or '/dev/tty.usbserial-000154' on macOS. By default, the SDK will auto-detect the port. | |
| ##### ENABLE_DEBUG | |
| > For HW debugging, configure ENABLE\_DEBUG=1. See the document [AIROC™-Hardware-Debugging](https://infineon.github.io/btsdk-docs/BT-SDK/AIROC-Hardware-Debugging.pdf) for more information. This setting configures GPIO for SWD.<br> | |
| > | |
| - CYW920819EVB-02/CYW920820EVB-02: SWD signals are shared with D4 and D5, see SW9 in schematics. | |
| - CYBT-213043-MESH/CYBT-213043-EVAL/CYBT-253059-EVAL: SWD signals are routed to P12=SWDCK and P13=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe. | |
| - CYBT-223058-EVAL/CYW920835M2EVB-01/CYBT-243053-EVAL/CYBLE-343072-EVAL-M2B/CYBLE-333074-EVAL-M2B/CYBLE-343072-MESH: SWD signals are routed to P02=SWDCK and P03=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe. | |
| - CYBT-263065-EVAL/CYBT-273063-EVAL: SWD signals are routed to P02=SWDCK and P04=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe. | |
| - CYBT-343026-EVAL/CYBT-353027-EVAL/CYBT-333047-EVAL: SWD signals are routed to P11=SWDCK and P15=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe. | |
| - CYBT-413055-EVAL/CYBT-413061-EVAL: SWD signals are routed to P16=SWDCK and P17=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe. | |
| - CYW989820EVB-01: SWDCK (P02) is routed to the J13 DEBUG connector, but not SWDIO. Add a wire from J10 pin 3 (PUART CTS) to J13 pin 2 to connect GPIO P10 to SWDIO. | |
| - CYW920719B2Q40EVB-01: PUART RX/TX signals are shared with SWDCK and SWDIO. Remove RX and TX jumpers on J10 when using SWD. PUART and SWD cannot be used simultaneously on this board unless these pins are changed from the default configuration. | |
| - CYW920721M2EVK-02/CYW920721M2EVB-03: The default setup uses P03 for SWDIO and P05 for SWDCK. Check the position of SW15 if using JLink with the DEBUG connector. | |
| - CYW920706WCDEVAL: SWD debugging requires fly-wire connections. The default setup P15 (J22 pin 3 or J24 pin 1) for SWDIO and P11 (J23 pin 5 | |
| or J22 pin 4) for SWDCK. | |
| - CYW920736M2EVB-01: SWD hardware debugging requires fly-wire connections. The only option is using P14 for SWDCK and P15 for SWDIO. These route to Arduino header J2, A1 and A0. These can be fly-wired to Arduino header J4, D4 and D5. From there the signals connect to the KitProg3 SWD bridge. In addition, the debug macros (SETUP\_APP\_FOR\_DEBUG\_IF\_DEBUG\_ENABLED and BUSY\_WAIT\_TILL\_MANUAL\_CONTINUE\_IF\_DEBUG\_ENABLED) are placed in sparinit.c in code common to all applications for this device. Most applications for this device call bleprofile\_GPIOInit() in subsequent code, overwriting the SWD pin configuration. To use hardware debugging after the call to bleprofile\_GPIOInit(), place the debug macros in code after that call. | |
| - CYW943012B2EVK-01: SWD signals are shared with D4 and D5. | |
| - CYW920820M2EVB-01 & CYW920819M2EVB-01: The default setup uses P03 for SWDIO and P02 for SWDCK. Check the position of SW15 if using JLink with the DEBUG connector. | |
| - CYW989820M2EVB-01: SWD hardware debugging requires a fly-wire connection to use P14 for SWDIO. P2 is connected directly to SWDCK / ARD_D4. Fly-wire P14 / ARD_D8 on J3.10 to J4.3 / ARD_D5 to connect SWDIO. | |
| - SWD hardware debugging is not supported on the following: | |

| **Using the ModusToolbox™ Eclipse IDE** | |
| 1. Install ModusToolbox™ 2.2 (or higher). | |
| 2. In the ModusToolbox™ Eclipse IDE, click the **New Application** link in the Quick Panel (or, use **File > New > ModusToolbox IDE Application**). | |
| 3. Pick your board for BTSDK under AIROC™ Bluetooth® BSPs. | |
| 4. Select the application in the IDE. | |
| 5. In the Quick Panel, select **Build** to build the application. | |
| 6. To program the board (download the application), select **Program** in the Launches section of the Quick Panel. | |
| **Using command line** | |
| 1. Install ModusToolbox™ 2.2 (or higher). | |
| 2. On Windows, use Cygwin from \ModusToolbox\tools_2.x\modus-shell\Cygwin.bat to build apps. | |
| 3. Use the tool 'project-creator-cli' under \ModusToolbox\tools_2.x\project-creator\ to create your application.<br/> | |
| > project-creator-cli --board-id (BSP) --app-id (appid) -d (dir) <br/> | |
| See 'project-creator-cli --help' for useful options to list all available BSPs, and all available apps per BSP.<br/> | |
| For example:<br/> | |
| > project-creator-cli --app-id mtb-example-btsdk-empty --board-id CYW920706WCDEVAL -d .<br/> | |
| 4. To build the app call make build. For example:<br/> | |
| > cd mtb-examples-btsdk-empty<br/> | |
| > make build<br/> | |
| 5. To program (download to) the board, call:<br/> | |
| > make qprogram<br/> | |
| 6. To build and program (download to) the board, call:<br/> | |
| > make program<br/><br> | |
| Note: make program = make build + make qprogram | |
| ## Downloading an application to a board | |
| If you have issues downloading to the board, follow the steps below: | |
| - Press and hold the 'Recover' button on the board. | |
| - Press and hold the 'Reset' button on the board. | |
| - Release the 'Reset' button. | |
| - After one second, release the 'Recover' button. | |
| Note: this is only applicable to boards that download application images to FLASH storage. Boards that only support RAM download (DIRECT_LOAD) such as CYW9M2BASE-43012BT can be power cycled to boot from ROM. | |
| ## Over The Air (OTA) Firmware Upgrade | |
| Applications that support OTA upgrade can be updated via the peer OTA app in:<br> | |
| >\<Workspace Dir>\mtb\_shared\wiced\_btsdk\tools\btsdk-peer-apps-ota<br> | |
| See the readme.txt file located in the above folder for instructions.<br> | |
| To generate the OTA image for the app, configure OTA\_FW\_UPGRADE=1 in the app | |
| makefile, or append OTA\_FW\_UPGRADE=1 to a build command line, for example: | |
| > make PLATFORM=CYW920706WCDEVAL OTA\_FW\_UPGRADE=1 build<br> | |
| This will the generate \<app>.bin file in the 'build' folder. | |

| > Use this GUI tool to create and configure the LE GATT Database and the BR/EDR SDP Database, generated as source code for your | |
| application.<br> | |
| Run this tool from the Tools section of the ModusToolbox™ QuickPanel, or | |
| by right-clicking a project in the Project Explorer pane and selecting | |
| the ModusToolbox™ context menu.<br> | |
| It is supported on Windows, Linux and macOS.<br> | |
| Location: \<Install Dir>\tools_2.x\bt-configurator | |
| ## Tracing | |
| To view application traces, there are 2 methods available. Note that the | |
| application needs to configure the tracing options.<br> | |
| 1. "WICED Peripheral UART" - Open this port on your computer using a serial port | |
| utility such as TeraTerm or PuTTY (usually using 115200 baud rate for non-Mesh apps, and 921600 for Mesh apps).<br> | |
| 2. "WICED HCI UART" - Open this port on your computer using the Client Control | |
| application mentioned above (usually using 3M baud rate). Then run the BTSpy | |
| utility mentioned above. | |
| ## Using BSPs (platforms) | |
| BTSDK BSPs are located in the \mtb\_shared\wiced\_btsdk\dev-kit\bsp\ folder by default. | |
| #### a. Selecting an alternative BSP | |
| The application makefile has a default BSP. See "TARGET". The makefile also has a list of other BSPs supported by the application. See "SUPPORTED_TARGETS". To select an alternative BSP, use Library Manager from the Quick Panel to deselect the current BSP and select an alternate BSP. Then right-click the newly selected BSP and choose 'Set Active'. This will automatically update TARGET in the application makefile. | |
| #### b. Custom BSP | |
| **Complete BSP** | |
| To create and use a complete custom BSP that you want to use in applications, perform the following steps: | |
| 1. Select an existing BSP created through ModusToolbox™ Project Creator that you wish to use as a template. | |
| 2. Make a copy in the same folder and rename it. For example mtb\_shared\wiced\_btsdk\dev-kit\bsp\TARGET\_mybsp.<br/> | |
| **Note:** This can be done in the system File Explorer and then refresh the workspace in ModusToolbox™ to see the new project. Delete the .git sub-folder from the newly copied folder before refreshing in Eclipse. | |
| If done in the IDE, an error dialog may appear complaining about items in the .git folder being out of sync. This can be resolved by deleting the .git sub-folder in the newly copied folder. | |
| 3. In the new mtb\_shared\wiced\_btsdk\dev-kit\bsp\TARGET\_mybsp\release-vX.X.X\ folder, rename the existing/original (BSP).mk file to mybsp.mk. | |
| 4. In the application makefile, set TARGET=mybsp and add it to SUPPORTED\_TARGETS. | |
| 5. In the application libs folder, edit the mtb.mk file and replace all instances of the template BSP name string with 'mybsp'. | |
| 6. Update design.modus for your custom BSP if needed using the **Device Configurator** link under **Configurators** in the Quick Panel. | |
| 7. Update the application makefile as needed for other custom BSP specific attributes and build the application. | |
| **Custom Pin Configuration Only - Multiple Apps** | |
| To create a custom pin configuration to be used by multiple applications using an existing BSP that supports Device Configurator, perform the following steps: | |
| 1. Create a folder COMPONENT\_(CUSTOM)\_design\_modus in the existing BSP folder. For example mtb\_shared\wiced\_btsdk\dev-kit\bsp\TARGET\_CYW920819EVB-02\release-vX.X.X\COMPONENT\_my\_design\_modus | |
| 2. Copy the file design.modus from the reference BSP COMPONENT\_bsp\_design\_modus folder under mtb\_shared\wiced\_btsdk\dev-kit\bsp\ and place the file in the newly created COMPONENT\_(CUSTOM)\_design\_modus folder. | |
| 3. In the application makefile, add the following two lines<br/> | |
| DISABLE\_COMPONENTS+=bsp\_design\_modus<br/> | |
| COMPONENTS+=(CUSTOM)\_design\_modus<br/> | |
| (for example COMPONENTS+=my\_design\_modus) | |
| 4. Update design.modus for your custom pin configuration if needed using the **Device Configurator** link under **Configurators** in the Quick Panel. | |
| 5. Building of the application will generate pin configuration source code under a GeneratedSource folder in the new COMPONENT\_(CUSTOM)\_design\_modus folder. | |
| **Custom Pin Configuration Only - Per App** | |
| To create a custom configuration to be used by a single application from an existing BSP that supports Device Configurator, perform the following steps: | |
| 1. Create a folder COMPONENT\_(BSP)\_design\_modus in your application. For example COMPONENT\_CYW920721M2EVK-02\_design\_modus | |
| 2. Copy the file design.modus from the reference BSP under mtb\_shared\wiced\_btsdk\dev-kit\bsp\ and place the file in this folder. | |
| 3. In the application makefile, add the following two lines<br/> | |
| DISABLE\_COMPONENTS+=bsp\_design\_modus<br/> | |
| COMPONENTS+=(BSP)\_design\_modus<br/> | |
| (for example COMPONENTS+=CYW920721M2EVK-02\_design\_modus) | |
| 4. Update design.modus for your custom pin configuration if needed using the **Device Configurator** link under **Configurators** in the Quick Panel. | |
| 5. Building of the application will generate pin configuration source code under the GeneratedSource folder in your application. | |
| ## Using libraries | |
| The libraries needed by the app can be found in in the mtb\_shared\wiced\_btsdk\dev-kit\libraries folder. To add an additional library to your application, launch the Library Manager from the Quick Panel to add a library. Then update the makefile variable "COMPONENTS" of your application to include the library. For example:<br/> | |
| COMPONENTS += fw\_upgrade\_lib | |
