How to improve bluetooth connection
I have a chinese smartwatch, called GV30, I think they all are similar ( so it may be similar to a more common u8 ) . The bluetooth connection is very low and weak, it reaches barely 1 m from phone before disconnecting ! I don't know if it's a manufacturing defect or it's a lack of chinese-made, but i want to improve it. I have no warranty, but I am thinking about to repair myself, maybe improving antenna' s lenght or replacing bluetooth module. What do you recommend me ?
