RE: NRF52840 central application Found 16-bit service but characteristic UUID is 0

Hi Bjørn,

Thanks for your time in looking at this question.

I am able to find the 128-bit characteristic already.

The solution is to add the UUID in reversed during sd_ble_uuid_vs_add().

Hi Lian,

Just to make sure that I have understood correctly:

You have a peripheral device that has a service with a 16-bit UUID, that service has two characteristics, one with a 16-bit UUID and the second with a 128-bit UUID. You have a nRF52840 device were you are running the pc-ble-driver connectivity firmware on and creating a Central application on Windows PC using pc-ble-driver. The issue is that you're not able to properly discover the Service and the characteristics?

If you could share some relevant code snippets then that would be helpful.

Best regards

Bjørn
