Increase the timeout to 3 seconds

Browse Source 
The BLE communication is significant slower than usb-serial. The first
BLE data packet of each response often takes longer than one second to
arrive. This causes the first attempt to fail with a timeout. The second
attempt will appear to succeed, because it actually receives the
response of the first attempt. But now the next command will fail,
because it will receive the response of the second attempt of the
previous command.

Increasing the timeout and adding an extra delay before retrying, avoids
this problem.
