Problem with connection on HOTT reciver

[heinerle]

Hi,

my next problem is the connection with Graupner Hott reciver.
My Groundcontrol: qgroundcontrol-sumd-v111
My Hexfile: aqv6.7v100-rev2.hex

In Flashing and setup i choise Radio Type SUMD and transmit to the Controller, but a cant see any changes if i move my controlstics.

What make i wrong?

What about a inverter when using SUMD which is mentioned on h**p://autoquad.org/wiki/wiki/getting-started/configuring-autoquad-flightcontroller/radio-options/

I'm using a Graupner MC-20 and a GR-24. The MC-20 is set to SUMD OF 12 and the Spectrum Sbus is connected to output 8 of the GR-24 including the inverter.

Although I'm using the released firmware 6.7 and all the calibration and calculations are done, the communication seems not to work.

Do you have any recommendations what I can check what could be wrong?

FYI: here´s Fred´s original thread concerning the Graupner SUMD:

btw: I´ve updated the Wiki. You don´t need an inverter for SUMD. Just connect ch8 to the Spektrum port GND and signal and pick up the 5V from a motor port like shown in the image above.
