APP_UART_DATA_READY reset nRF52832

[daniel]

Hi, I am a beginner programmer and I have the next problem.

I am working with nRF52832 SDK 12.2 trying to send AT commands to an ESP8266. I send the AT commands byte by byte through UART which I managed with APP_UART_TX_EMPTY. Then I receive the ESP8266 response in APP_UART_DATA_READY and when I should get a response such as \r\nOK\r\n I get half data instead. When it happens the nRF52 resets. The ESP8266 is working rigth because I check the response with a terminal so I think I could be a problem with UART. Any help will be appreciated.

Thanks in advance

What is "half" data? You get the data through the uart_event_handle() correct? You check the received data with scope or use segger RTT to display them in the RTT viewer?

[Matt]

Do you have flow control enabled? Can you test with a lower baudrate?

[daniel]

I meant I receive \r\nO or \r\nOK instead of \r\nOK\r\n. I have checked the data with both digital analyzer and segger RTT and I get the completely response from modem so it is \r\nOK\r\n. The problem I have is when I am getting the data through the uart_event_handle() in APP_UART_DATA_READY nRF52 resets. I have tried with lower baudrates and it do the same, but I am not using flow control.

Thanks Matt

What is a reset reason?It may help you ,sd_power_reset_reason_get(&reset_reason);

[daniel]

You are rigth, I have used sd_power_reset_reason_get(&reset_reason) and I have got reset reason = 0x00000004, I am seeking how to solve it but I don't find any clu.

Thanks Max
