How have you verified that the communication from the nRF52832 is as expected, but not the other way - are you using a logic analyzer?<br />Which pins are you using for the UART communication, and how do you know that the quectel module is properly receiving the data?<br /><br /></p> [quote user=""]when i receive the AT respone&nbsp; from quectel nrf52832 shows junk data..[/quote] <p>What exactly are you receiving from your quectel module, and how is it different from what you would have expected?<br /><br />Furthermore, are you working with a nRF52 DK or a custom module? Are you working out of an SDK example? - if so, which example?<br />Which SDK version are you working with?<br /><br />Best regards,<br />Karl</p><div style="clear:both;"></div>
