Hello,
I always observe 4.0xxV from the li-po battery attached after when thingy52 stopped charging.
I think this problem maybe because of output current from the battery...
On our project we're using a Raspberry Pi 3 compute module with custom hardware and 2x nRF51 SoC running HCI from Zephyr.
We'll be delivering more than 150 of those devices...
Hello! Can I use one of the gpio pin as power source directly for other MC on my board (hx711 - ADC with current consumption in normal mode 1.5ma (from datasheet)). I understand...
Hello, long story short:
You now must use write request instead of write to write the CCCD descriptor.
Allegedly (according to a nordic employee) both types...
