I have two remote gsm switches. Their developing company has stopped operations and both the devices are now not working. I opened those devices and found onboard atmega328p paired with sim900 gsm module. There is one mini usb port that and its data pins are connected to tx/rx pins of atmega328p. I am trying to program this board with my own code to make it work again. I tried to connect atmega with ch340 usb to ttl adapter but not able to program. Can anybody please help me to reprogram this board.
Hi,This a modem module, i mean you can drive it via an arduino or via gpio from other board.look at this post for a way of programmind the atmega328p via another arduino :https://forum.arduino.cc/index.php?topic=618343.0Regards, and good researchsOliver Beirne Expected forum : SOC Design forum for a module at... i think

No: it's about an AVR 8-bit microcontroller - not even an ARM architecture at all!
