AWS IoT Device SDK Port Library

This library is a port layer implementation for the Infineon MQTT and HTTP Client libraries to work with the AWS-IoT-Device-SDK-Embedded-C library on Infineon connectivity-enabled MCU platforms. These library APIs are not expected to be called by application directly. See the MQTT and HTTP Client library documentation for more details.

OTA Support

This aws-iot-device-sdk-port layer implementation also supports PAL APIs required by AWS-IoT-Device-SDK-Embedded-C OTA. By default, OTA support is disabled. To enable OTA support follow below steps.

  1. Add the CY_OTA_FLASH_SUPPORT macro in the application Makefile. The Makefile entry should look like as follows:

    DEFINES+=CY_OTA_FLASH_SUPPORT

  2. Create a .mtb files for anycloud-ota and serial-flash as follows and add .mtb file along with other dependent library .mtb files:

    anycloud-ota.mtb: https://github.com/Infineon/anycloud-ota#release-v4.1.0#$$ASSET_REPO$$/anycloud-ota/ serial-flash.mtb: https://github.com/Infineon/serial-flash#latest-v1.X#$$ASSET_REPO$$/serial-flash/

  3. Execute the make getlibs command.

  4. The reference file ./configs/ota_config.h that is bundled with this library provides the default configurations required for the AWS IoT device SDK OTA library. Copy the reference file ./configs/ota_config.h to application root folder, tune the OTA configuaration parameter as required by application and add OTA signing certificate to macro AWS_IOT_OTA_SIGNING_CERT.

  5. Build application using make build command.
