How to use the Firmware Updater through the App Loader.

The new firmware updater app says load a .hex_app file.
But when you download the : espruino_2v10.142_banglejs2.zip the isn't a .hex_app file ?
How is this mean't to work ?

This is cutting edge feature and needs new bootloader you probably don't have, unless you built everything from source and flashed over swd. And then you would also have the app_hex file which is produced while building the firmware.

To sum it up - it is not ready yet.

Btw the hex file could be also generated by running bin2hex tool on the .bin which is inside the zip you have. However you need to specify starting address fo bin2hex conversion which is 0x26000 for Bangle2.

As @fanoush says - it may not even work unless you update the bootloader (which that app can do, but I haven't supplied hex files for it).

Eventually the idea is for it to be able to load the ZIP file, decompress it and work directly off the files inside, but for now if you want to use it you need to build firmwares yourself (and then you'll get an app_hex file)

Ok, if its not ready that's fine.
