Hi Kenneth,

I have downloaded the 'nrf_sniffer_for_bluetooth_le_3.0.0.zip' file and gone through the documentation. If i understand correctly, one needs to run the sniffer code (sniffer_pca10040.hex) on sniffer node and place it between the two devices that are communicating to start recording the log in wireshark.

I could not get the sniffer log as i have only one nRF52-DK board. could you please do the needful.

Thanks and Regards,

Malti

I have not had time to recreate this, are you able to make the sniffer log for me using nRF sniffer v3?

Please find the attached firmware. Please note that you need to use it with soft device S332.

Have you tried to search for 'Error 133 (0x85): GATT ERROR devzone' to see if there are any relevant issues that may apply here?

I would really like an on-air sniffer log, if you don't have the possibility to do yourself, is there any way you can send me firmware I may run on an nRF52-DK to try to recreate your issue by using nRF Connect on a mobile phone?

Hi Kenneth,

Please find the attached log file from the 'nRF_Logger' App.

We have seen the error related details(error code, line number and file name) during development, But not seeing any details about this error, It just sends the message 'Disconnected' to serial terminal. Is there anything we need to enable/configure to get details about all the errors.

Hello,

Do you have an on-air sniffer log?

Is there any asserts in the nRF52 application? Check fault handler for error code, line number and file name. https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/an-introduction-to-error-handling-in-nrf5-projects
