PPPos client will it support SIM7600 module? (IDFGH-3256) #5250

I am trying to make use of PPPos protocol between ESP32-WROOM-32D and SIM7600CE-T module. But I am getting run time error, when i flash the program. Please let me know whether PPPos protocol supports SIM7600 or not.

Hi @poojavernekar

I've skimmed through the SIM7600 datasheet and AFAICT it doesn't seem to support PPP mode. Looking at the supported AT commands, there's just a socket interface. You can use the socket related AT commands with the esp-modem component to some extent, but would need to implement these specific commands. There's no such example in esp-idf demonstrating TCP/IP socket networking with SIM7600 or similar.

Ok thank you david,

I have worked with AT commands, by making use of uart_asys_tx_rx example program, where i passed AT commands, its working fine and I am getting responses. Now the task is to share data using MQTT protocol,( ESP32-WROOM-32D and SIM7600 modem) But my problem is I dont want to use WIFI connection of ESP32, i want to share or establish internet gateway connection from SIM7600 to ESP32 module, So i was trying to make use of PPPos protocol. Please suggest is there any way to achieve internet gateway connection from SIM7600 to ESP32??

Hey tried to resolve the issue by establishing gateway connection between SIM7600 and ESP32 using AT commands, below mentioned link https://m2msupport.net/m2msupport/data-call-at-commands-to-set-up-gprsedgeumtslte-data-call/
