First, Thank you for reading this topic.
I'm developing mini APM v3.1 using ArduPilot 3.2.1 for my master's degree theis.
I have several problems like can't connect MavLink.
First problem is uploaded firmware. That can connect Mission Planner through MavLink. but, gps is work.
I think that problem occured by "baud rate", but I didn't find that.Second is Bluetooth telemetry. Using bluetooth module is HC-06, set baud rate 57600, and connect APM through 5V,GND and crossed TX,RX but, is not working.
It can't connect to Mission Planner through MavLink, and Alert and showing message "No heatbeat received"
I didn't find any thing of this problem.Finally problem is "GY-86", is the combination module included MPU6050, HMC5883, and MS5611.
I'm using GPS module "Ublox Neo-6M"(Using protocol NMEA, baud rate 9600, no built-in compass).
Thus, 5V and GND between GY-86 and Neo-6M is parallelly connected to mini APM. (I already cut JP1)
And TX,RX is crossed connected to Neo-6M, and SCL, SDA is serial connected to GY-86.
However, GY-86 Module does not working. actuallty I mean, compass(magnetometer) HMC5883 in that module.
How can I connect compass through I2C?I want to collect pretty nice solution.
Thanks.
