AT BLE Commands

[eyalc@traffilog.com]

I am not sure is the right forum to discuss on the AT commands.

But I am facing with difficult to open communication channel between UART (Based on At commands) and Ble Client (Android Phone APP).
I succeded to Transmit data from the Phone but not from the UART - getting 'ERROR'.
I tried to Use SPP Mod and write to Caricaristic and nothing helps. also used the last FW
you can see below my commands log.

Thanks for the help!

Maybe the problem is that none of characteristics you are trying to set as RX characteristics has descriptor 0x2902?
Try this:

Code: Select all

AT+BLESPPCFG=1,1,1,1,6 or AT+BLESPPCFG=1,1,1,1,7

Its only guessing, because i didnt try AT commands.
