SiK 1.8.1 HM-TRP firmware issues

Posted by John Hutchison on December 19, 2013 at 6:09pm

Upgraded both of my 915MHz radios from 1.7 to 1.8.1.

Linking the radios using MP now takes almost 1.5 minutes, with numerous messages like "Already got Parameter X". Once linked the update rate of the horizontal situation indicator lags for several seconds. Using the same settings when downgraded back to 1.7 and quick linkup with fast update rate on MP. Used MavLink and Low Latency settings with same issue on 1.8.1.

MP version: 1.2.90

APM: 2.6

3DR 915 2gen: 1.7 & 1.8.1 (both radios are running identical fw ver during each test)

I also had major problems with v1.8.1, mostly it just wouldn't connect. I've gone back to v1.7.

Note: If anyone needs to go back to v1.7 you need to find an old Mission Planner version, I used v1.2.55 which will load v1.7 when you click "Upload firmware (local)"

Have you tried to restore the factory settings. This can be done using MP or a console connection to the port and typing the following command sequence

AT&F - Set the factory Settings

AT&W - Write those settings to EEPROM

ATZ - reboot the radio

to connect on mac I use screen /dev/cu.usbserial-XXXXXXXX 57600 use ctrl-a,ctrl-\ and pres Y to quite screen when done.

XXXXXXXX is the unique identifier for your radio on your system

Upgraded module to 1.8.1 (don't know why) :(

Now I cant connect module anymore.

I forced bootloader and loaded firmware again, but that didn't solve the issue.

Where can I download version 1.7
