There was an almost total code rewrite, so at that time the USB SpiffChorder became the BLE FeatherChorder. The reworked code for the feather was written with Charles Chen and is available on GitHub.

If you then turn off the software radio, stop advertising, or you try and put the board into its lowest power state by issuing sd_power_system_off(), the blue light either keeps blinking or goes solidly on. Bluetooth is not advertising or the board is in a very low power state, but the blue led stays on. There should be a way to fix this! text/html 2025-05-11T01:05:31+00:00 priestdo (priestdo@undisclosed.example.com)
