Hello,
When we use 868.xml file, then the buttons in the GCS are not activated and also the settings tab is absent. When we choose default_imu_9k6.xml file, everything is OK. We are using paparazzi version: v4.9_devel-812-g8f341f0-dirty.
Do we forget something?
Best regards,
Refik

[Paparazzi-devel] digi 868 modem |

Dear all,
We get digi 868 oem modems. Today, we tried them for the first time. Our RC
transmitter is at 433MHz. After take-off, we couln't use RC transmitter. The
power of 868 modem was 100mW.
It also corrupted our ublox GPS module. When we pushed the launch and take-off
buttons, take-off is written in the GCS. At that moment, GPS gave a pos. acc.
of 3.6m. However, the autopilot did not give any throttle in auto2. We removed
the modem, and connected serial cable, then it gave throttle. In some tests, it
also immediately jumped from takeoff to standby, although we did not take off.
1. I think that 100mW power was too large. What power level do you recommend
for communicating within 5km range?
2. Do you recommend to use a filter for RC_receiver and modem? Do I need to
change RC frequency to 2.4GHz?
3. Do you think that the take off problem was due to GPS error or EMI-EMC
problem at the autopilot?
4. Is there a tool which calculates the duty cycle of modem depending on the
telemetry xml file?
Best regards,
Refik
