"If it does not work at the first try, don't forget to try to switch the tx and Rx lines. Sometimes, the pinout-descriptions are missleading. Sometimes "Tx" means output, but on some modules "Tx" is input, so "connect to Tx".
One of my china radios…"
"Thanks, Arthur. Now, at least I know, how DP determinates which BT device to use.
I'll try to unpair all other devices and see if it works then.
Still uncommon that they did not implement a device selection."
"I tried to build the same with an HC-07 bluetooth module, but I have 2 problems:
1.) If you access the bluetooth COM-port in MS Windows, it takes a few seconds ti establish the connection. Mission Planner seems to timeout too early and will not…"
"I also can't get v1.1 working. :-(
Wiring and module itself are definitely correct, because I can acquire images from the sensor with the test pde and the python script, but I also only get zeros for movement. (but different values for squal (64,…"
"I tried it but had no luck.
It's kinda working, but as I turn it, mission planner shows me drifting the direction anywhere but not as it should.
When turning, North is showing every time in an other direction. :-(
If I remember right, the datasheet…"
"Regarding the 2nd call: even without having detailed info about the programming structure of Arducopter, from programmer's sight of view, your second attempt sounds the best for me: to tell the sensor to make another measuring soon after reading the…"
"Thanks for your quick reply, Randy.
I just downloaded the Ardupilot Arduino SDK and synced with git. (master branch)
In the rangefinder lib, I saw that the XL I2C seems somehow implemented. ...by you :-)
"I'm planning to add a Sonar sensor to my Hex.
Please, can anyone tell me, if i2c sensors are already implemented and useable in Arducopter 3.0.1 ?!
I really searched all over the internet but could not find any information regarding this.
Or should…"
