nRF Connect "NO CONNECTION"

[PhilMeier]

Hello everyone,

i am created my own UUID Service with a characteristic. I used this tutorial --> https://github.com/bjornspockeli/custom_ble_service_example
Code is working but now i can not connect my nRF52840 DK with nRF Connect anymore.

Can somebody help me please ??

Hello,

What does it look like when you try to connect? Do you get any information from the log on your nRF52840 DK? Does it say anything in nRF Connect? Are you using nRF Connect for Desktop or Mobile?

Do you see the device in nRF Connect at all? In other words, does the device advertise?

I used the desktop and mobile version.
I can see the device and i can click on the "Connect" Button.
But it doesn't connect.

Ok. Did you check the from for the nRF DK? Alternatively a sniffer log, but I believe the nRF DK log is easier to check if you haven't used the nRF sniffer yet.

My guess is that one of the calls to APP_ERROR_CHECK(err_code) in your application receives an err_code != 0. What SDK version do you use?

Best regards,
