I wanted to test the android app that is being developed as my laptop is too clunky to haul around. Trouble is I have an external GPS/Mag connected and I'm using a PPM reciever. Can I still attach an HC05 BT module to my Revo for bluetooth access? If so, where would I connect the RX/TX/PWR connections to exactly?

Best is to attach Bluetooth to OPLink modem. How you power OPLink modem is up to you. I connect Flexi VCC and GND to my Taranis, enable power for external module while I keep using internal one. This powers my OPLlink modem and in turn powers Bluetooth on Main-port. OPlink has to be configured to for telemetry on main-port. Really works great with Android App in the field.

Another option is to use Receiver port (Flexi-IO) which has PPM and Telemetry lines refer to table at https://librepilot.atlassian.net/wiki/display/LPDOC/Revolution+Configuration
But using Bluetooth with OPLink is better as it gives you better range (Connection diagram attached).

Interesting. Would have never thought about doing that. Will have to look into it. Thanks for the info.

You can also connect the Bluetooth module to the flexiIO port (receiver port), there is Tx/Rx pins and you simply need to setup the Receiver port to PPM+Telemetry
