[General] BLE service to leverage IOT BLE data transfer service

[shijinjose]

Briefly summarize the issue being raised
We want to create a BLE service which leverage the IOT BLE Data transfer service for all data communication with peer mobile device.
Is there a documentation or guidance available on how to integrate this custom service with Amazon FreeRTOS.

Describe the desired outcome
create a new service similler to WIFI provisioning or MQTT over BLE.

System information

• Hardware board: [ ESP32 ]

Hi @shijinjose

Is this in regard to a particular release of amazon-freertos, or with latest main? Instructions may be fairly similar.

There is a Adding a New Service section in our BLE documentation. Our BLE abstraction is just a shim and reuses standard BT/BLE nomenclature from the spec.

We already provide a RX/TX type service you can reference, or possibly use, which is used for our mqtt_ble demos. Though it has additional GATT attributes you may not be interested in. Regardless you can see how this service defines the gatt server attributes, installs, and services updates with callbacks.
