I use RS Solutions GSM Terminal for uploading compiled python scripts into my 863 PY/GPS Module.
First of all, I tested the module with AT commands and get OK response. After that I upload .pyo files and get an error:
My RS-232 cable is 9 pin connected and I think there is no synchronisation problem. In addition, script size is not big. (max 2 KB)
So, what is the problem?
Thanks for your concern.
