BLE Advertising/Connection Interval

Hi hmolesworth,

I actually plan on using my chip without the DC-DC converter as I am only making a simple Bluetooth remote controller. However, I did manage to drive my power down significantly (into the uA range) with smarter use of the UART service.

Thanks for your time 🙂

Have a look at the suggestions I made in this post regarding enabling the internal DC-DC convertor vs internal LDO, and also UART power consumption when entering sleep.

Hi,

I actually managed to solve my own issue. I was trying to flash in a new program with the PPK still attached. After I removed the PPK and shorted the two pins of P22 (nRF Current Measurement pins), I was able to flash in new code that reflected the change.

I'm still having issues with reducing power draw because even with a much larger advertising interval, average power consumption is still around 1.8mA which is far too high.
