Flashing Blend 2 with Hex File


I’m trying to flash the Blend 2 with an hex file created from an arduino sketch, either over the air (OTA) or through micro usb. Does anyone have a link or program that allows me to do that?


Hi @stomper209,

Keep pressing the bootloader button as mentioned here, actually you need wire a button between the pin 4 and GND, then power up the Blend2, the Blend2 then stays in the DFU mode, which will broadcast a DFU service for OTA uploading application using nRF Toolbox App.

If you’re going to upload application through micro USB, why not just connecting your Blend2 to computer and simply clicking on the upload button to upload the sketch to Blend2.

Best regards,
