Hi,

You can use nRF Connect for Desktop to connect your device to the PC. If this does not suit your needs, you need to provide more details on what you want to achieve.

Best regards,

You need a nRF5x DK or Dongle, flashed with the correct connectivity firmware, to use with nRF Connect to be able to connect other devices with BLE. I'm not familiar with the error or serial numbers you posted, but my guess would be that you have a UART connection between your PC and the board, and you tried to use this with nRF Connect? nRF Connect is only written to work with our DK boards with Segger J-Link chips or our own USB CDC ACM on the nRF52840 dongle, it may not work as intended with other boards/connections
