WLI Piccolo speed out by 100km/h

Joystick3 years ago

Hi,

I've tested a Piccolo Hybrid device from Wireless Links and my server show speed as 100km/h faster. If traveling at 60km/h, speed on server is indicated as 600km/h.
I've completed the test on various speeds to confirm that it consistently showing 100km/h faster than what I am actually traveling.
Does anyone else have the same issue with other WLI devices or can this perhaps be a issue unique to the Piccolo Hybrid devices?

Meant to say that it appears as if speed on server side show the actual speed multiplied by 10km/h, therefore when traveling at 60km/h my server show 600km/h.

Do you have some HEX samples and protocol documentation?

Hi Anton,

Hex samples below from when traveling at approx 25 to 30 km/h. I will ask the supplier to send a copy of the protocol documentation.
