Keyboard Function

we_6096453246

I am currently integrating keyboard functionality into a mouse firmware running in 2.4GHz proprietary mode. I am encountering an issue with long-press key repeats. While the host OS initially generates continuous characters, the input stops after approximately 2 seconds.

I have identified that the dongle firmware forces a 'key release' (sending zero data) after 2 seconds of inactivity to manage state. However, continuously sending 'key down' reports from the mouse to the dongle to prevent this timeout causes the RF FIFO to flood, dropping the mouse report rate from 1000 Hz to ~800 Hz.

How can I maintain the key press state on the dongle/host without effecting the report rate? Currently the mouse/keyboard data are sent seperately. Do advise or guide over this issue.
