Hello pktron

We too are facing the problem as you had faced. The connect disconnect happens immediately.

We have nrf52810 in our custom board and is using internal RC oscillator. May i request you to share your experiences with the problem and how you guys resolved it?

Really looking forward to your reply as the project in our case too have gone in the critical situation.

Happy to help, and thank you for sharing the solution. Please open a new case if you need help with your antenna.

Hi,

We have managed to zero down the problem to problems in soldering the components on the board, and the matching capacitors. Now that problem is solved.

We still are having some problems with antenna range, but that is also probably due to the soldering again. We are still exploring.

Thanks for your kind support

Hi,

Disconnect error 8 is as you may know "Connection Timeout" which according to the specification indicates that the link supervision timeout
has expired for a given connection. It sounds like it is the central that throws you this error?

It could be that your peripheral application has stalled. Have you debugged your code to see what the code may be doing when the disconnect occurs?

Are you able to provide a sniffer trace? You can use a spare Nordic development kit and our Sniffer solution.
