Modify the channel in the receiving mode, call the "nrf_esb_stop_rx" function in the "nrf_esb_event_handler" function, but what if the "if (m_nrf_esb_mainstate == NRF_ESB_STATE_PRX...
Hey Devs,
Would someone be able to tell me the power draw on the Thingy? How long will the onboard battery (1440 mAh) last on it?
Help is appreciated.
Thanks,...
Hi, I am developing firmware to run on a custom board using the nRF52810-CAAA chip. I need to meet very strict lower power consumption thresholds, and need to very precisely...
We are in development of a wearable ecg medical device. We want to add 4g low power capability. The device is a patch worn by patients 24/7 up to 30 days. Our current requirements...
