I am trying to establish connection of external MCU with EC200U-CN.
I have got M2M Data sim with me which means I will have to establish ‘PPP’ mode to transfer data instead of normal AT - GPRS commands flow.
Can you please guide me with the M2M sim activation and PPP mode working from start till end so that I can start communicating with the server through MQTT pub sub.
Pls send me lasted firmware for EC200U-CNAA.
We have about 30pcs stuck at firmware version A01 - it not support PPP conmection.

Thank you!
