Hi all,
I am working on a personal project and recently received the custom PCB, assembled the parts and started testing. It has a BC26 modem connected to a ST micro-controller via the main UART interface.
Upon power up, the MCU receives the following via the UART
F1: 0000 0000
V0: 0000 0000 [0001]
00: 0006 000C
01: 0000 0000
U0: 0000 0001 [0000]
T0: 0000 00B4
Leaving the BROM
Then I send AT
expecting back a OK
but I don’t receive anything. I tried ATI
, ATE1
but never received anything from the modem other than the above mentioned strings upon power up or reset.
Does anyone have any idea of what could be wrong? Or what I could be missing?
Regards,
Sakthi
