I recently picked up a "WePower BY20D" from a local seller. It's an all-in-one (excluding battery) front hub kit from a Chinese manufacturer named LVBU. I would normally steer clear, but the seller is local and offers a one-year warranty while only being $550 NZD including a bottle battery. It's my first ebike, and I quite like it, but I want to tinker a bit.
I found a binary in the bike's bluetooth app APK, which I assume is a firmware blob. I'm looking for help figuring out what device this binary is for, and a way to disassemble it. IDA Pro doesn't recognize it. Here are the first 0x240 bytes: https://i.imgur.com/cTCmDZN.png
If you've got any ideas, please let me know If it's allowed by the mods, I can upload the 60KB binary.
