Preface

microhard P900 Data transmission

One 、 connection

Radio TX Connect to flight control RX,RX Connect to flight control TX,5V and GND Just connect it correspondingly

Two 、 Data transmission configuration

First in configuration mode

AT&F7 Set up the host
AT&F8 Set slave
Different slave device settings ATS105 Equal to different values

Set up the node network ：ATS104= network number ;

Set baud rate with ATS102
ATS102=1 115200
=2 57600

Check the configuration ：AT&V
Save configuration ：AT&W

If you want to set different master nodes corresponding to different slave nodes , Will be a kind of ATS104 Set to the same

After setting, use AT&W preservation

AT&V Check the configuration

3、 ... and 、 Ground station configuration

If the ground station is not automatically connected to flight control , You can add connections manually

Four 、 common problem

p900 Data transmission is intermittent
reason ：
Output back short circuit
terms of settlement ：
Remove the double-sided tape on the back

The time delay of one to many communication is relatively large
reason ：
Too much data
terms of settlement ：
Reduce the traffic of master and slave nodes
