HE910 garbage out

  1. Something strange has happened, this is a rough sequence of actions:

    I’ve started sending data in command mode (with `#SSEND`).

    Attempted to close the connection while still in data sending mode (before sending `0x26`), got echo in response, but no `OK` (makes sense, I was still sending data to an end-point). At this point I’ve shut down the device with the ON_OFF pin.

    Now whenever I send the `AT` command, I get this in response:

    0x00 0xF0 0x16 0x51 0x92 0x02 0x00 0x1A 0x00 0x00 0x00 0x20 0x11 0x0C 0x09 0x00 0x0C 0x8F 0x56 0x49 0x00 0x00 0xB0 0xFF 0xFF

    I’ve tried power-cycling it, removing power fo long periods of time, but nothing helps.
