@dlabun @sandeepmistry @jeanmatthieud 2 years have since passed and wondered if the arduino-nRF5 has resolved the energy consumption issue? See this pull request still not merged, guess the nRF51822 high...

@alxgarza you are more than welcome to check other [see bottom] discussions related to power consumption. I think it is quite easy to reach proper power saving to your needs:...

No I haven't try that since running a crystal usually increases sleep power consumption, unless you would like to sacrifice some power for accurate timing during sleep. Frankly I would...

OMG @LaZsolt you are right. I used your code > https://github.com/dbuezas/lgt8fx/issues/202#issuecomment-1419681782 and got **0.67uA (670nA)!** The best sleep current I ever got on any MCUs including ATtiny, ATmega, STM32, GD32,...
