I'm currently working on u-blox Nina B302 and I'm trying out program examples from the nRF52 SDK on an evaluation board.
To try out BLE connections, I'm using the nRF Connect v3.0.0 software with the Bluetooth Low Energy application (v2.3.0) as recommended.
I downloaded my code onto the EVK board and launched the BLE app to test the connection.
The board appears in the 'Select Device' drop down list with the appropriate serial port (it is connected to my PC with USB), but when I select it, I get the following sequence of messages in the log:
Application data folder: C:\Users\...\AppData\Roaming\nrfconnect\pc-nrfconnect-ble
Validating connectivity firmware for device with serial number 000483065974...
Error while setting up device 000483065974: Cannot read property 'toLowerCase' of undefined
Device closed.
I could not find any solutions except to attempt to update the BLE app or the nRF Connect software, which I did, but the error remained.
I tried reinstalling both, but the result is the same.
EDIT:
As some of the replies/comments suggested, I tried installing previous versions (2.6.0 and 2.7.0) of the nRF Connect software, but the problem was that the BLE app requires you to update the nRF Connect software.
The pseudo-solution I found was simply to use the mobile nRF Connect app on my Android phone. I am able to connect to my U-Blox microcontroller and test out some of the examples from the SDK. I'm still having some issues with the Nordic UART Service, but I'll keep you posted for any changes.
Thanks for the advice, I hope for a final solution or a better work-around soon.
