Hi everyone, Just built my first ever eskateboard last night. It is the BKB Duo kit, with the Dual FSESC 4.20 Plus VESC. The kit came with a bluetooth module which I believe is called an NRF51 bluetooth module. Here is a photo of it:
The issue I’m having is that the BKB directions say to plug this into the port labelled C2 on the VESC (shown in photo). This did not work (no light on module and no bluetooth signal) so I plugged it into the C1 port and it lit up, my xmatic app found it but said “Connecting to default device, connecting to VESC, Failed to connect, retrying…”. My phone listed the bluetooth module as visible.
I decided to download the VESC Tool to try to see if there was a setting causing the module to not work correctly. After connecting the VESC Tool to my VESC, the bluetooth module no longer works on C1 or C2, and I can’t even see a light on it anymore. I did not run a firmware update or a motor wizard… I was careful not to.
