Hi Team..,

Hello,

iam using nrf52832 interface with quectel.iam using uart communication..the problem is when i transmit the AT commands nRF to Quectel that is working fine.

Could you elaborate on the behavior you are seeing? How have you verified that the communication from the nRF52832 is as expected, but not the other way - are you using a logic analyzer?
Which pins are you using for the UART communication, and how do you know that the quectel module is properly receiving the data?

when i receive the AT respone  from quectel nrf52832 shows junk data..

What exactly are you receiving from your quectel module, and how is it different from what you would have expected?

Furthermore, are you working with a nRF52 DK or a custom module? Are you working out of an SDK example? - if so, which example?
Which SDK version are you working with?

Best regards,
Karl
