AWS OTA with Custom Publish and Subscribe


I'm trying to implement AWS OTA; however, I am using the Quectel modem's built-in Publish and Subscribe. I have a wrapper around collecting subscription data and publishing. Does anyone have some insight on how to connect a custom pub/sub to the aws ota agent?

Hi hans. The OTA library has several dependencies that need to be satisfied to port it:

You can find an OTA demo here: And an example of the setup of the interface here:

That all said, and without knowing the details of which Quectel modem you're using, I'm wondering if this is the best way forward? A lot of work has already been done with the Quectel BG96 to abstract at the TCP level rather than MQTT:
