3DR radio telemetry

Posted by Enrico on November 21, 2015 at 3:54am

Hi all,

I'm trying too add Telemetry to my BBBMINI. 

Radios are both connected. 

From Planner, I can see both, Local and Remote (FW ver. SIK 1.9 on HM-TRP) but then, no communication with Arducopter. (Of course i added -C /dev/ttyO4).

Any clue? Should i use Voltage adapter? (5 <-> 3.3)? (in this case i hope everything is still working...)

Thanks and have fun 

Enrico.

    Hi,

    Swapped RX-TX and now it works.
    Tags, on the other side of PCB, are in the opposite position, compared to connector pins...

    Thanks..

    Hi Enrico, as you can see here https://store.3drobotics.com/products/3dr-radio-set, the 3DR radio has a 3.3 Volt I/O, no level shifters are necessary.

    I also recommend what Marcin write, check the connection between the radio and the BBBMINI. 3dr radio RX has to be connected to BBBMINI TX, 3dr radio TX to BBBMINI RX.

    Best regards

    Mirko
