Unable to load the firmware on my micro:bit #11

Closed srcr closed 4 years ago

srcr commented 4 years ago

I'm trying to load the firmware from the dist directory to my micro:bit but this keeps failing. Off course I'm in maintenance mode and i have switched back and forth between the original firmware versions 0250 en 0253.

This is the .hex file I'm loading:

Name: btlejack-firmware-microbit.hex
Size: 470092 bytes (459 KiB)
SHA256: FE61EEF08BC64E4898CC9ABE047465A3B17A536BCFD39233FA2398B1654AA989

after dropping it on the storage the micro:bit resets and restarts in maintenance mode. At this point I see the FAIL.TXT on the storage with the following content:

The hex file you dropped isn't compatible with this mode or device. Are you in MAINTENANCE mode? See HELP FAQ.HTM

My micro:bit has version v1.3 B on the print.

Any advice would be appreciated.

Btlejack firmware is designed to be uploaded the normal way, not in maintenance mode. Maintenance mode is used to upgrade the interface firmware that runs on a secondary chip in charge of the USB interface. Connect your micro:bit WITHOUT pressing the reset button, and drop btlejack firmware on the associated mass storage device that shows up (should be named MICROBIT).

Ok, I thought the code was firmware. let me try it and see if I can get it going.

Things work like a charm. I'm currently sniffing my phone <-> FitBit traffic. Naming this project btlejack-firmware put me in the wrong mind set that I needed to write this as firmware.
