[TMC] nRF52810 BLE disconnection when used as central-next

sean over 5 years ago

Hi team,

Here is the previous ticket

One of my customer TMC is using our nRF52810 in a BLE key project for central role, their development environment is:

nRF52810-QCAA/ SDK 14.2/ Softdevice S132 v5.1 (BLE key as central to connect with lock in peripheral role)

Disconnection issue description:

When running software on their own board, cannot connect with peripheral, and error code is 0x3e; Change another board, same issue happens...

But when running same software on our PCA10040 (Change nRF52832-QFAA to nRF52810-QFAA), everything is normal...

Log is as below

2nd Red Block is log on their own board.

We suspect it can be a hardware issue, so you can refer attached Layout and SCH in attachment

Here is the sniffer trace file

Could you please give some suggestion for this case? Thanks for your attention!

Thanks!
