Crius AIO Pro with 3DRadio 433 Mhz Telemetry

[Quad FRITZ]

Hello-

how to connect this module to the Crius AIO Pro?
I connected it to TX3/RX3 (works with Megapirate NG) and changed the serial speed in the config.h to #define SERIAL_COM_SPEED 57600 (3DRs are configured accordingly)
I connected the copter to a LiPo, the 3DRobot ground module to USB and opened the WinGui with the correct USB and boud settings.
The 3DR modules connect (solid green) and transmit some data (red blinking on both modules)- but no data is transmitted from the AIO Pro to the WinGui (no update of data in gui,...)
I read the serial ports are all common-lized (I use MultiWii_2_1), so it should work without explicitly choosing the serial port for this module from what I would expect (?)- but it does not....

I would expect I rather have to connect to a differnet serial port on the AIO or choose the according serial_port in the MultiWii SW SOMEWHERE (where???)?

Please let me know how to:

- connect the hardware
- set up the SW (MultiWii_2_1) and the WinGui
- set up the 3DRadio modules
- if there is anything else I am missing

- and- which serial port is the on- board FTDI connected to? any possible conflicts here?

THANKS a LOT

Hello,
on 2.1 you can use only one (first) serial port for connecting GUI and you set that port to desired baud, so you must connect your 3DRadio to RX0/TX0 (that one is AFAIK also shared with onboard FDTI/USB).

On later _shared verisions you have option to use all serial ports.... and set speed for every one.

Code: Select all

/******                Serial com speed    *********************************/
    /* This is the speed of the serial interfaces */
    #define SERIAL0_COM_SPEED 19200
    #define SERIAL1_COM_SPEED 115200
    #define SERIAL2_COM_SPEED 115200
    #define SERIAL3_COM_SPEED 19200
