I am using gatttool on Raspberry PI to connect to a BLE peripheral. The connection fails with the error message "connect error: Too many levels of symbolic links (40)"
The following is the command & response log obtained with gatttool.
pi@raspberrypi:~ $ sudo gatttool -b 20:70:6a:10:01:81 -I [20:70:6a:10:01:81][LE]> connect Attempting to connect to 20:70:6a:10:01:81 Error: connect error: Too many levels of symbolic links (40)
What is the issue here? Thanks

I had the same issue, and bringing the hci0 interface down and up helped me.
sudo hciconfig hci0 down/up
