TinyDuino Processors & TinyShields / Re: Nordic BLE w/TinyDuino: connection lost on battery power, OK on USB power
« on: March 10, 2017, 05:18:40 PM »
The problem is basically with the button battery that I've been using. I happen to have several TinyDuino's that run with the larger Li ion batteries sold by Tiny Circuits. I tried one with the 290 mAh battery and now it works fine. Maintained Bluetooth connection for many hours before I simply just stopped it on manually. I'm not a Bluetooth LE expert, but my understanding is that in trying to conserve power it goes into low power mode when not transmitting or receiving. Possibly the button battery cannot supply a surge current associated with the turning on ?? Or maybe there is another reason.
