OTA HTTP Interface

The OTA PAL interface definition.

OTA HTTP Overview

The OTA MQTT interface is a set of APIs that must be implemented by a library to enable the OTA library to download a file block by connecting to a pre-signed url and fetching data blocks.

The OTA MQTT interface is defined in ota_mqtt_interface.h.

The functions that must be implemented are:

• OTA MQTT Subscribe
• OTA MQTT Unsubscribe
• OTA MQTT Publish

These functions can be grouped into the structure OtaHttpInterface_t and passed to OtaInterfaces_t to represent the MQTT interface.

OtaHttpInterface_t httpInterface;
httpInterface.init = httpInit;
httpInterface.request = httpRequest;
httpInterface.deinit = httpDeinit;
 
 .....
 
OtaInterfaces_t otaInterfaces;
otaInterfaces.http = httpInterface
 
 .....
 
OTA_Init( &otaBuffer,
          &otaInterfaces,
          ( CLIENT_IDENTIFIER ),
          otaAppCallback )
