Update - Using APRSdroid with the Kenwood TM-D710 via Bluetooth

Somehow I managed to kill the Bluetooth module I was using (reverse polarity maybe?) and of course couldn’t find another - I’m surprised there isn’t demand for such a module, maybe a project for another time.

Anyway, took a slightly different approach this time. Used a standard HC-05 type module and mounted it in the head. Wired up to some +5v I found and connected to the input side of the RS-232 driver included in the radio head (connected to the 2.5mm socket).

Using APRSdroid with the Kenwood TM-D710 via Bluetooth

Quick afternoon project to hook the TM-D710 up to a Galaxy Tab 2 8.0 I recently mounted in the car. APRSdroid can consume and display waypoints using the Kenwood proprietary format outputted by the radio, all that was needed was to get the data to the tablet.

For this, a small Bluetooth - serial adaptor was mounted in a project box. It’s a variation of the popular “HC-05” module as was labelled “BTM-05”. It includes both a MAX232 and a voltage regulator, so nothing further was required for power and data.
