Please describe your issue below:

Bluetooth performance seems very poor. I have been using a bluetooth keyboard and trackpad which is very laggy to the point of being unuseable. I have also tried to attach an Ipega controller. The controller works perfectly with my android phone. With the Edge2, it either won’t display as an available device, won’t pair or will say it’s paired but won’t do anything or immediately disconnect.

You can connect the bluetooth antenna to Edge2, which can enhance the signal

I have the ARM PC. I presume the antenna is installed in the case?


The position of the bluetooth antenna is in the red box as shown in the figure below
