3 years ago Part of the delay in solaar show is unavoidable - it is communicating with the device and that takes time. You could write a simple script to send a "report battery" command to your keyboard via the receiver. To see the command, run solaar show -dd and look for the communication just before the report on BATTERY VOLTAGE. The voltage level is a 16-bit number in the response from the device, which is followed by a byte of flags. You will also see Solaar's interpretation of the message just after the response.
This is going to be specific to your keyboard and receiver.
