Hi @show2go, are you running this on a Raspberry Pi, using the RPI's builtin Bluetooth hardware?
If so: At least some time ago, the builtin Bluetooth hardware of the RPI was causing strange problems that went away when using a different Bluetooth adapter. So if you happen to own a Bluetooth 4-capable Bluetooth USB dongle, you could try attaching it to your Raspberry Pi and see if it makes a difference when you use that Bluetooth adapter instead. (See here).

Something else you could try is turning debug output on, by placing DEBUG=* in front of the keyble-sendcommand command to get some more clues what might be the problem.

Hi @oyooyo , thanks for your reply...

i will try the debug mode.
Thank you!
