Custom PCB: How to quick check if BLE is working? nRF51822AB

[Stephan]

Hi guys,

I hope you can answer my question: I made myself a custom pcb for testing purpose. I can program the nRF51822 just fine. Thats the actual state right now.

In combination with the nRF51822-EK: How can I just quick check if my BLE is working? I just want to kinda sniff, if I got RF-Output. It doesn't need to be a connection. I just want to be sure, that RF works before I'm getting into SW-debugging and API and stuff like that.

How can I check that? Is there a plain, simple solution?

Regards, Stephan

Hi Stephan,

See if the answer in this post can help you (Wrong clocksource used during softdevice_enable): devzone.nordicsemi.com/.../what-could-make-ble-sample-applications-not-work,-but-radio-works-ok

This really sounds like a separate question from the one originally posted here, but if the chip works nicely except for radio, I guess it's the 16 MHz crystal being mounted incorrectly. If the chip functions correctly, including proprietary radio examples, but BLE softdevice initialization hangs, Pål is most likely on the right track below, with regard to low frequency clock source used.

Pål,

I don't believe it! It works! It truly works! :) :) :) :) Thank you SO much! This one made me mad for the last days because I could not figure out what was wrong! Seriously, thank you SO SO much!

This one should be "pinned" somewhere where other users might find it fast!

It's early in the morning but you just made my day!

No problem, I'm really glad to be of assistance

it would help others if you could mark my answer as accepted, because then other people can look at the symptoms and find the solution. :)
