Bluetooth keyboard Support
- Install reset firmware on both halves of the keyboard. (download)
- ReDOX Wireless firmware – default (download)
- Then install the firmware you are using on the right and left halves.
- In order for the right half of the keyboard to connect with the left half, which is the master, you must press the reset button and bring the left half closer to the right.
ZMK currently supports Bluetooth connection interval as low as 7.5ms, which gives an average Bluetooth latency of 3.75ms.
A device connected wireless to the central (whether the central is a dongle or one of the keyboard halves) will experience approximately twice the aforementioned latency as data has to travel twice.
The Nordic microprocessor used by our keyboards include support for a proprietary Bluetooth extension called Low Latency Packet Mode that allows the connection interval to be as low as 1ms. Combined with 1ms of USB polling and 1ms of processing time, it’s theoretically possible to achieve total latency around 3ms. While this is something that can be added via a firmware upgrade, at the moment there is no concrete plans of implementing it as our users haven’t found the current level of latency to be problematic.
If using one of the keyboard halves (such as the left half) is used as the central in place of an external dongle, that half can be used directly over USB as a USB keyboard. However it will continue to communicate with the other half wirelessly.
No. As the keyboard is wireless, it is important to find the right balance between the number of LEDs and maximizing the battery life.
