On my board I run TB Direct Drive, Unity without a power button, Metrp pro and Hoyt St Puck
For power on/off on the board I use auto shut off and detect wheel spin for turning on.
On the first try the board and remote always connect with no issue and the connection is solid, but after I take a short break and restart the board, the remote will not connect at all. So I wait a few minutes, give it another go and suddenly it works again beautfully.
I genuinely have no idea what could be causing it. Maybe something about how the unity shuts down, maybe how it starts up, maybe a mixture of both…
Anybody have experienced something similar? Anybody know a way for me to diagnose this further?
Only thing I can think of is the powering up of the puck reciver. unity not putting out a stable 3.3 or 5v on the rail when using push to start befor the batery takes over
If it’s that Fix could be a little filter on the reciver supply. Or a drain on the reciver so It electronics don’t hold a charge
That actually might be it, cause my metr usually doesn’t show “powered off” its shows under voltage after the board turns off
As somebody whose most complicated electronics DIY project was changing the unity from 3.5 to 5.5mm bullets and to an xt90 connector, is that filter/drain something I could do without fear of smoking my hardware or should I have somebody else do that?
Also do you know of any resources that I could check out?
I had a very similar issue. I found it to be the little connector on the receiver was the issue. Vibrations would cause a disconnect. I ended up removing that little black square and soldering the receiver straight to the esc. No more issues.
Btw, I had the issue on every esc I used and soldered the receiver to a xenith.
You will always get that error, as the metr doesnt know you decided to turn off the unity, it only reads voltage and reports it out to you.
So that is not an issue, happens the same with the original unity bt module.
My fear was that it might be disconnecting, but it does so exactly every second time I start the board, makes no problems during the ride at all and not moving the board at all fixes it suddenly?
Unless there is something funky going on with built up tension being relieved I am having a hard time imagining that
