Setup, Windows 10 PC, nRF Connect for Desktop 3.12.0, BLE App v4.0.0
The windows nRF Connect for Desktop BLE Application on Windows 10 no longer works properly. I've managed to get it to connect to a nRF52840DK eventually by doing the following:
1. Connect nRF82840DK to PC
2. Disable segger mass storage device in device manager
3. Cycle the power on the nRF52840DK
4. Run nrfjprog --recover from the command line tools
5. Open nRF Connect for desktop
6. Open the BLE app (v4.0.0)
7. Select the DK
8. App says 'firmware must be programmed' even though it was previously programmed with this
9. The BLE app now works as usual, except:
10. After using for a short time, I get the error "Disconnected from device B8:1F:5E:FF:F9:02, reason: BLE_HCI_STATUS_CODE_LMP_RESPONSE_TIMEOUT"
11. Every time I connect the DK, I get the message that the firmware needs to be programmed.
Previous to this, it wouldn't work at all, it would say it had programmed the firmware, then would give error messages saying invalid response from device.
Prior to these problems appearing everything worked normally. This problem has occurred simultaneously on a number of PCs in our office.
I have attached logs of where it works but times out and where the firmware programming fails, meaning I need to perform nrfjprog --recover
