NCS 1.5.1: ESB RX event doesn't wake Zephyr from idle.

[Niziak]

With current ESB implementation I'm not able to delegate radio event to other thread or workqueue.
Kernels stays in idle (tickless kernel) and all radio frames are lost.
One solution is to disable tickless kernel or implement direct ISR according to Zephyr doc (in attached patch).

Hi Wojciech

Thanks a lot for the heads up

This might be an oversight when the ESB library was ported from the nRF5 SDK. I will check with the developers and see if this is something that should be changed in the implementation. 

Best regards

Hi again

The developer confirmed your findings, and will ensure that we patch this in a future update. 

Once again thanks a lot for bringing this to our attention

Best regards
Torbjørn
