good Morning Jorgen,

I have a issue with profil uart, I use the application note "getting_srated_nRF5SDK_keil.pdf".

The compilation of the sources works fine but when I want to load "softdevices" in the PCA10056 kit, keil v5.30 shows me error: Flash Download

failed - 'Cortex M4'. For information I don't compile when I select target with flashs140_nrf52_7.2.0_softdevice ? I don't understand where is the issue ?

thank you for help

Alexandre

Good morning Jorgen,

OK for the information HID Keyboard Application and UART/Serial Port. In fact for UART emulation the idea is open a virtual COM port for example with windows 10 and Putty. I will come back to you if I have difficulty to implemented the 2 services.

Thank you very much

Alexandre

Hi,

We do not have any examples in our SDK combining these two services, however, we have separate examples for each:

Combining the services in one example should be quite simple, mainly copying the functions related to the service from one example to the other.

Let me know if you are facing any specific issues with combining.

Not sure if you are aware already, but there is no common defined UART emulation/serial service for BLE. The Nordic UART Service (NUS) used in the example above is our custom UART service. The service interaction needs to be handled in applications on the other end of the link, it is typically not supported natively in OSes like Android, Windows, etc.

Best regards,
Jørgen
