Feather M0 Bluefruit as Central?

Can the nRF51822 on the Feather M0 Bluefruit LE operate as a central device?

Looking to use another bluetooth LE 'camera button' to turn on an LED controlled by my Feather.

Re: Changing battery charge rate from a Bluefruit Feather 32

I too tried to increase the charge rate. I believe the 10k resistor is the vertical component at the very center of the attached image. I added a 2k resistor in parallel to try to get the maximum charge rate but the charge rate has not changed. I guess it is possible that the lipo charger used on th...

Re: bluefruit nRF52 Ble Midi controller

Hathatch - can you give me any advice on this? My supplier says they'll take the board back for a refund, so I'm looking to do that if I can't get it working soon.

It would be good to know if anyone can get bluetooth midi working on the nRF52 by following the Adafruit Ble midi controller tutorial?
