Hi Guys,
A followed Hexor's HOWTO (thanks for it) and I was able to successfully burn new firmware. From CCLoader I got :
... 510 511 512 Upload successfully!
File closed!
Comport closed!
Now I am able to send AT and got OK as response. But problem is that I got OK on every AT command:
AT+HELP? -> OK
AT+RENEW -> OK
AT+ADDR? -> OK
I am able to detect flashed module using another CC41a so I think that is working.
Did anybody observed similar behavior of flashed module?
Thank for help!
