We have been suffering very slow connection rates with SIK Radio Telemetry, upwards of 30s for the initial parameter download. We are using them in a Pixhawk2.1 with 1.7.3 firmware.
Last time we used these radios it was in a Pixhawk 1 ( we have been using pixracers in the in between period) and I remember having a reasonable quick parameter download then.
I have read in some Ardupilot forums that ECC was related to the issue,
So have disabled it setting
as explained here:
This has made a huge difference, now parameter download takes less than a couple of seconds...
Of course disabling ECC (Error correction checking) is a bit of a worry, so just wondering:
Anyone has experience disabling ECC ?
Another suggestion in threads is to keep ECC enabled but reducing the serial baudrate to half of the airdate ( ECC increases the amount of data sent apparently).
However I'm reluctant to do that as I don't know how to change baud rate in QGControl or wether it as autodetect?
Any thoughts on this second option ?
Lastly I'm wondering it this issue has just appeared because the volume of mavlink data been sent is much larger? We are using more sensors now. .. vision navigation, px4flow
