ble is just transport layer, if the actual data is encrypted, you can get nothing.
One of our device FW at first transmit raw data through gatt service, then folk at gadget bridge reverse engineer it, which does not sound good to stakeholder, so we have to encrypt the data between phone-device.
- Ductapemaster 2mo agoQuite possible transport is encrypted, but that can likely be overcome with some RE on the Android app. Given the price of this piece of hardware, it's likely recoverable with moderate effort. At least worth a try.
- mrheosuper 2mo agoyeah, my point is "1 night and $20 of Claude token" maybe not enough. Also you dont really need the nrf52840 dongle if you want sniffing(Also unlikely to work after the pairing process is done), you can use btsnoop on Android phone to record data, then analyze it with wireshark.
- Ductapemaster 2mo agoYou're right, I was representing a best-case scenario with an intention to be inspiring. And yes, the Android approach works too and I have done exactly that with Claude previously. The BLE dongle is however a platform-independent approach.
