I bought a Mint about 3 weeks ago and have had a lot of trouble with it. Initially it would connect via BT, but often I would have problems like you describe. The other day I measured the output voltages on the 3.3V and 5V power pins and they were at least .5V low. I couldn't get my voltmeter probes on the battery output pins so I don't know what it makes but I suspect it is low.
Have a look at this thread. <https://groups.google.com/forum/#!topic/ioio-users/DlcIBHwErEw> Ytai says that the Mint is not a standard IOIO board, it has a step-up circuit that is supposed to boost the battery to the 5V minimum required by the board. But looking at your findings, I am thinking that my battery (and yours) never has put out enough voltage to power up the board properly and if so that means the BT dongle is probably also not getting enough and will be flaky or inoperative. Another problem with the Mint is that it is obsolete downrev hardware, it is a V1 board and cannot now be easily upgraded to the current firmware level (which you definitely do want). I recommend that you save yourself a lot of trouble and return the Mint. Get yourself the IOIO-OTG board and immediately upgrade the firmware to the most recent version. You will have to come up with your own power supply and mount/enclosure for the board, which is inconvenient, but in my opinion it is the right way to go. -- You received this message because you are subscribed to the Google Groups "ioio-users" group.
