Hi Jian,

The old UART 2.0 app is deprecated (over 3-4 years since last update). I strongly recommend using the nRF-Toolbox app, and use the UART function there instead. If you need the source code, then it can be found here.

If that does not fix the problem, it might be that Android has cached previous services from the device, and do not do a full service discovery. Try then to choose DFU in the Toolbox app, and connect. The app automatically does a service discovery when the dfu service isn't found.

Sorry, I don't know. I switched from nordic to esp32. Tools and IDF works better for me and was easier to understand. And documentation is very clear.

Also the forum works better.

Wish you good luck with nordic :-)

Hi, Mark:

I have the same problem, what is your phone os version?

Have you modified the code in example to make it work!

I don't know what was scred up. With nRF Connect I could see the hts profile, that I tried some time before. But that should be erased by the nRFgo "full erase"?!

Anyway, I did do some resets on eval board, programmed some different examples by IAR and tried again the UART example, now it works....magic.
