UPDATE Realized I can connect via serial super easy on mac - this is the result: https://pastebin.com/raw/ThHYgeYw I entered firstboot -y; sync; reboot and now its AP popping up again. did the wifi setup via ssh this time. Seems to all work now... I'll leave this here, maybe someone finds it useful. Some more info here is that the serial drivers offered for mac are crashing on M1 big sur but are apparently not even needed, the omega shows up as /dev/tty.usbserial-0001

@Anders-Öster said in Omega mini dock: Thanks to both, I wil try with a wire. @György-Farkas - by pressing the reset button duriing boot you can access a menu and choose to flash the Omega 2+ from USB even when it is bricked as I understand it.

Thanks for the detailed reply. I went with option 3 and managed to fit some 0805 onto the 0603 pads and it works as expected. Thanks again.

@Kit-Bishop I am definitely interested in the alternatives and will probably end up trying one of those. I guess I just don't want my mini dock to go to waste ¯\(ツ)/¯

@Dylan-Schreier Use the first Serial Port to help debug. https://community.onion.io/topic/1329/tip-switch-the-omega-to-verbose

@Ken-Conrad A voltage-divider is basically just two resistors. Remove the one that goes to GND and replace the other one with a 0 Ohm-one or remove it and short the pads. I can't tell you which resistors they are on the dock, however, without actually having the dock.

I received the replacement mini dock yesterday ( March 9) and now I'll try to put it to use.

@Matthias-Nowak We seem to generally concur that there are some issues etc. that could be fruitfully addressed. One final comment on all this in relation to pins 15, 16 and 17: While these pins on the Omega and Omega2 are not exposed on the Expansion Dock, they are used on the Expansion Dock for control of the expansion LED: Pin 15 - LED blue Pin 16 - LED green Pin 17 - LED red However, note also that with the Power Dock there is no LED and so these pins are neither used nor exposed. It seems a shame to have 3 pins not exposed just to control an onboard LED that isn't always available

@Clement-Ho Oh, I can solder. I've got a few onion proto boards on backorder (I think they are in the mail). The form factor with the power dock is too tight. It is actually a tug of war between the board and the case where either the case flexes or the board warps. Either way its not ideal. The mini dock would be amazing if I could get a standard PCB board to work.

@Ruud-van-der-Pluijm Nope, sorry! You need a USB hub to have two USB ports

@esunayg, I'm just plugging the Omega into the mini dock with nothing other than power through the micro-USB port. My other two Omega units run just slightly warm,

@Kit-Bishop yep I know about it. This will be of course much better and non-invasive way. But up to my knowledge is not yet available and this hack was done in 5 minutes

@Dan-Diemer Yeah, we recommend additional venting for any Mini Dock cases. The density of the circuits is much higher than on the Expansion Dock and the Mini Dock voltage regulation circuit also produces more heat than that on the Expansion Dock.

Yea, I thought if ppl not like the case, they do at least like the giraffe It is part of my concept to rescue things on my desk. The USB key is so small ...

@Kit-Bishop said: https://community.onion.io/topic/3/mini-port-expansion that's what i thought... well I'm waiting for the battery expansion, until then I'll probably jam the wires into the headers. Thanks @Kit-Bishop

Hi @Yanir-Nulman, I'm really sorry about the poor quality of the switch. Is your mini dock broken in the ON position? If it is in the OFF position, would you be able to try to switch it to the ON position with a needle? As long as the Mini dock is on the ON position, it shouldn't affect the functioning of the Omega.

@Rajesh-L The Omega stopped working after a factory reset?
