Firmware for MMDVM Pi-Hat (BI7JTA)

Hi Folks:

running some bench tests with a VR2VYE & BI7JTA MMDVM Full Duplex Pi-Hat (Version 10). The current firmware is:

MMDVM protocol version: 1, description: Nano_hotSPOT-v1.3.4 20180404 dual ADF7021 FW by CA6JAU GitID #fb8806e

Before I upgrade the FW, I'd like to get a copy of the bin or hex file for this exact version in case I need to rollback.

Any ideas where I can find this FW?

Thanks,

Ramesh, VA3UV, WA3UV, G4PNQ

You can find the Vendor's version here for your exact build (see link below), I *just* added support for those boards to the update tool on Pi-Star in the last couple of days... the firmware has been shipping with Pi-Star for a while, but the upgrade tool didn't have the options for those boards (it does now).
