David Cermak 7547267336 feat(modem): Add mqtt example in AT-only mode
Similar to pppos-client, but without PPP mode.
This uses standard mqtt client and a loopback service that forwards the
TCP traffic from localhost to the modem and vice-versa.
(next step is to create a dedicated tcp-transport layer for modem)
Console example uses DCE commandable to demontrate how to handle URC

ESP MODEM

Component Registry

The esp-modem component is a managed component for esp-idf that is used for communication with GSM/LTE modems that support AT commands and PPP protocol as a network interface.

Examples

Get started with one of the examples:

  • examples/pppos_client -- simple client implemented in C
  • examples/modem_console -- C++ example implementing simple terminal console with DCE commands
  • examples/ap_to_pppos -- this example focuses on the network connectivity of the esp-modem and provides a WiFi AP that forwards packets (and uses NAT) to and from the PPPoS connection.
  • examples/simple_cmux_client -- this example sets up the CMUX mode to talk to the modem using AT commands with simultaneously maintaining active network connection.
