This example enables Power saving mode in Sim70XX modem and tries to synchronise the sleep cycle of the modem with esp32. When the modem wakes up from PSM sleep it wakes up the esp32. While the modem is awake esp32 is set to light sleep. Closes: https://github.com/espressif/esp-protocols/issues/54
ESP MODEM
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 Cexamples/modem_console
-- C++ example implementing simple terminal console with DCE commandsexamples/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.
