LS on LINUX

I have been working with the LS for some time now since the conversion to Linux.

Without a doubt it seems like I am using a new unit. Time to start up and acquisition of a fixed position has decreased noticeably. Also the average number of engines seems to have increased. This all equates to faster surveys, increased efficiency and increased profit, particularly for those of us working on a lump sum basis rather than time and materials.

Great job Javad!

I also prefer the Linux version, but it still has some quirks. Today after starting up in base-rover
I staked out the base point to make sure everything was working right (it was). 5 minutes later when I arrived at my first control point the LS had lost its WiFi connection. Sometimes turning WiFi off and then on again works, but this time a hard reboot was required. Not devastating, but annoying nonetheless.

Hello Jim,
what is wifi network layout? Are you getting connection over MiFi device or it is over deployed wifi network in the region?

Same thing happened on Monday, base-rover starts out fine, but I drive 5 minutes to my first point and I have no connection. Turning the LS WiFi radio off and on again doesn't help. Rebooting the LS does, and then it works fine indefinitely. I haven't yet tried turning my phone's hotspot off and on, but will next time.

What I have found, is if the Rover, looses TCP connection to the BASE, I have to reboot the base, and then it works. The base will show the rover is connected, the rover shows its connected to the base, but there is no base coordinate and no corrections. Once the base is rebooted, everything goes back to normal. Here is a strange part, everyday around 2:30 - 3:30 EST, the base and rover, quit communicating, It has to be Verizon thing, but after the base is rebooted, everything works fine. RAMS is a life saver, I can reboot the base, and do not have to return to it. I am running LS to LS, so RAMS works in this case, so added benifit from LS to LS workflow.

I am fairly confident this has been reported as a known issue, concerning TCP base/rover setups. I am not sure if the radio has the same issue or not, as we use the radio very infrequently. My situation maybe completely different than yours, because I am running LS to LS.

If completely different, sorry, did not mean to hijack a thread.

They might be related problems, but different in manifestation. In my case, it's the LS that loses the WiFi connection and can't get it back without a reboot. I don't have to mess with the base at all to get going again.

I verified today that restarting the WiFi hotspot on my phone doesn't help. A reboot of the LS is the only fix I've found so far. The problem is annoying and consistently reproducible (at least on my unit), but at least the fix isn't too onerous.

About a year ago or so I unlocked the Cellular radio on the LS. All of the WiFi related connection problems disappeared and the system seemed to just work. I connect to the CRTN on a routine basis with no problems. No regrets on the unlock fee.
