iBeacon example doesn't work with nrf52840dongle or nrf52dk_nrf52832 with zephyr

[jeremyherbert]

I have checked out and built the iBeacon sample in zephyr (samples/bluetooth/ibeacon) for nrfconnect version 1.7.1. I tried building for both the nrf52840dongle and nrf52dk_nrf52832, but I can't find the beacon using the nRFConnect app on an iPad or an Android mobile phone. As far as I can tell, this firmware is simply not working. The output of the nrf52dk looks sensible:

I built and flashed using "west build --board=nrf52dk_nrf52832" and "west flash" for the nrf52dk. For the nrf52840dongle, I built using "west build --board=nrf52840dongle_nrf52840" (I made sure to delete the build folder before doing this so it would actually rebuild) and flashed using the nRF Connect for Desktop application. I have also attached the zephyr.hex for the nrf52dk.

6761.zephyr.hex

Could you please help me understand what I am doing wrong?

[jeremyherbert]

I have no idea why, but it started working for me now after I came back later and reflashed it. I'm going to chalk this one up to a glitch in the universe...

Hi 

Good to hear you found the issue. There is no reason these examples shouldn't work out of the box. I will consider the case closed then

Best regards
