If you have one of those heltec v3s and it keeps disconnecting from bluetooth, try soldering a 31mm piece to the coil next to where the power comes in. I just used a strand from a cat cable. It took 5 minutes and now my connection is solid. You want to short the coil parts. I just put a gob of solder in the coil and shoved the stripped end of the wire in there and that seemed to work. The surface tension of the solder filled up the coil part and it gives a solid mount for the wire.
