Hi, not sure if that’s possible but you can use [converter](https://www.keil.com/download/docs/7.asp) and then Particle CLI `particle flash --usb firmware.bin` ---

The .hex files are for use with a debugger. For Gen 2 devices, this can be a ST-LINK or ST-LINK clone USB stick. For all devices, it could also be a Particle Debugger or Segger J-LINK. ---
