@ayke@hachyderm.io I've used https://www.aliexpress.com/item/1005003693318567.html with https://www.aliexpress.com/item/1005006609750088.html Had to press the button to change the device class, add some udev extra rules so openocd is allowed to use it and was able to flash it with: openocd -c "interface cmsis-dap" -c "cmsis_dap_vid_pid 0x1a86 0x8011" -c "transport select swd" -f interface/cmsis-dap.cfg -f target/stm32l0.cfg -c 'program firmware.hex verify reset exit' FOTA works great on a good speaker, so a non-transparent clip is also fine: https://www.aliexpress.com/item/1005004251918008.html
