PPPoS simple client example

(See the README.md file in the upper level 'examples' directory for more information about examples.)

Overview

This example shows how to act as a MQTT client after the PPPoS channel created by using ESP-MQTT APIs.

How to use this example

See the README.md file in the upper level pppos directory for more information about the PPPoS examples.

USB DTE support

For USB enabled targets (ESP32-S2, ESP32-S3, or ESP32-P4), it is possible to connect to the modem device via USB.

  1. In menuconfig, navigate to Example Configuration->Type of serial connection to the modem and choose USB.
  2. Connect the modem USB signals to your ESP chip (pin 19 (DATA-) and 20 (DATA+) for ESP32-S2/S3).

USB example uses Quactel BG96 modem device. BG96 needs a positive pulse on its PWK pin to boot-up.

This example supports USB modem hot-plugging and reconnection.

Supported IDF versions

This example is only supported from v4.1, as this is the default dependency of esp-modem component.

USB example is supported from v4.4.
