By the way, is it the same "2.4GHz proprietary protocol" stack that this board supports?:

I'm thinking on buying that dev board instead of the typical NRF24L01+'s, seems like getting more bang for the buck since it supports ANT and other protocols, not just 2.4GHz.
The MDP-P905 does not turn on when connecting to this powerbank... are you sure that's the only requirement that's off on my setup?
But, but... my Trust powerbank is QC3.0 compatible, see the link above and/or screenshot below:

Bizarre, I guess I'll have to go for the barrel jack for now :/
I just received mine, and can confirm that it does not support PD or activate USB-C ports, at least on my unit. I'm looking into firmware updates, but I'm doubtful.
It's a shame because in my testing so far, it's otherwise perfect. I'm at a loss why they wouldn't have included it; combined with a 20V/5A capable USB-C/PD power bank you could have an incredible portable power supply.
I've actually already got a MakerHawk PD cable set to 20V and it works fine ... it just surprised me that given how much effort they clearly put into the product, they wouldn't add PD support. It seems like such an obvious feature for this kind of device and would eliminate one more thing we have to keep in our kit.

All that aside, my MDP-P905 is hosed now. The firmware upgrade failed, and now it won't boot past the DFU. I've tried flashing both v1.20.067 and v1.21.034 using both the .hex file, and the MDP_ADR.ADR + svn80.bin file (according to the readme). The .bin file actually succeeded (or at least the files were renamed to .SET and .RDY), but it still won't boot past the DFU.
I'll try emailing service@minidso.com to see if they have any suggestions.
Does anyone here know of any method to .. ehm.. factory reset.. or have any other suggestions?
PD version MDP-P905 is on the development.
It can't upgrade by software, need hardware change.
The firmware will open source soon.
M01 will open source code this year
P905 will be released a little later
MDP will release a new firmware in these two months,
Then I will consider first to open source M01
It can connect with base station only as far as 0,5m but maybe it just problem with my unit.
It would be theoretically easy to fix the P905 by just putting two 5.1k resistors inside (there are two CC pins in USB-C). I did make it work with a 5.1k resistor on a USB-C breakout board in series with the miniware, but the connector pins and the free space inside was way too small for me to succesfully fit that inside the housing.
