I have two VESC 4.12's running independently and both using FlipSky BLE modules to connect to VESC Tool on my Windows computer. Previously, these modules were able to connect to my computer simultaneously using two instances of VESC Tool, and I was able to change parameters and record realtime data from both simultaneously.
The other day, one of my VESC's was unplugged from the power supply when I switched it on, but it received power through the Spektrum AR620 receiver that both VESC's are connected to for receiving radio inputs. The VESC began to blink red as it was being powered by a low voltage, I'm assuming (The receiver plug into this VESC registers ~5V when the other VESC is powered). After this, neither BLE module will consistently connect with my computer, although they have been able to connect occasionally the great majority of the time VESC Tool will give the error "Connection Timed Out" when I try to connect.
I am struggling to find any rhyme or reason for why this issue is occurring now, and I'm not sure if it's connected to the low voltage issue I encountered the other day.
Any ideas for why this is happening?
Thanks
