Hi everyone,
I'm working on SIMCOM5218E and have some trouble about it. I have designed a GUI on PC and communicate with my SIMCOM device. Normally I have communicate from PC to device and from device to PC. But nowadays I could not .
I'm sending client connection from PC to device, device accept and I send some data AT+TCPWRITE from device to PC, it's OK but when I want to send some data from PC to device. Device could not receive data and get me CLOSED error.
I have read some thread and said the problem Sim card's 3G finished limit. I have controlled it's OK.
Has any idea about it?
