nRF52 DK clock issues

[Marius Heil]

Hello,

I have an nRF52 DK here that behaves strangely since a few days. Hardware id is 0xc7

When I boot it up with my firmware, sd_ble_enable takes around 2 seconds but returns an error code ok.

If I try to connect to another nRF52 DK, it reports a connection success, but directly disconnects with HCI error 0x3E, Connection failed to be established.

Advertising seems to work.

When I flash the nRF connect firmware on the board, it detects the firmware, but fails with NRF_ERROR_TIMEOUT.

What happened?

Thanks,

Marius

Hi,

Have you changed anything? 

Can you capture a sniffer trace so that I can have look at what is happening over the air when it fails to connect? Which SDK, Softdevice and example are you using?

As for the NRF_ERROR_TIMEOUT, how do you flash the connectivity firmware? Can you upload the log from nRF connect when this happen?
