NRF52820 dongle for gaming mouse

[blitz0145]

Hello, I am trying to develop a 1000 Hz wireless gaming mouse. The mouse has a NRF52832 onboard and the dongle has a NRF52820 on it. (Cannot switch to 52840)

I do know about Bluetooth LLPM, but I'm trying to avoid it since it is expensive in terms of power consumption + processing. 

I've tried using Gazell- was able to get the report rate up to 822 Hz; but it won't go beyond that. Could you suggest a Gazell configuration that will be able to push it to 1000 Hz?

I was also thinking of using Enhanced Shock Burst instead, will ESB perform better?

Also, in terms of power consumption, is Gazell/ ESB better than BLE?

Currently- USB is not enabled on the NRF52820, when it is enabled- will it significantly degrade the performance of whichever radio protocol I use?

Hi there, developing a 1000 Hz wireless gaming mouse sounds like an exciting challenge! For your issue, I think you could try tweaking the Gazell configuration to optimize the report rate. Enhanced Shock Burst (ESB) is also worth considering, as it might offer better performance in some cases. In terms of power consumption, Gazell and ESB are generally more efficient than BLE, but you’ll need to thoroughly test to ensure overall performance.
