Mike Fikes | Using an MFJ-407B keyer to drive Morse Chat mobile app with paddles @MikeFikes | Uploaded May 2023 | Updated October 2024, 2 hours ago.

The keyer is connected to a button on the nRF board on the left, which is acting as an HID keyboard, connected to the phone. The Morse Chat app is set to straight key mode while the keyer is taking care of the iambic paddle logic.
Much like the demo shown in youtu.be/_yfMRzepxrU, keyboard latency and jitter affects the ability to key the app effectively at high speed, but this can be mitigated by configuring the BLE parameters.
