We have just removed sim and tested with the following results
Android will connect to reach wifi but Reach2 app shows no receiver. Reach 3 shows receiver but cannot connect.
IP address via chrome app connects.
Seems pretty similar as before
Connects intermittently through reachview app.
Connects more reliably through ip address
Obviously correction or data share could not be tested with no sim and reach in hotspot mode.
We then reflashed firmware and tried tests again with similar results as before (reflashing doesnt seem to have changed problems)
Next we tried connecting the reachview to a hotspot created by the mobile device.
Apple - works intermittently (but this has always been the case as apple hotspot generation isnt reliable)
Android - connected perfectly through several power cycles of the RS2.
Reach 3 app working perfectly
Reach 2 app not showing receiver (tried several times before and after using reach3 app and also force closing apps etc)
In android with the mobile hotspot we also tested correction input via NTRIP and found the following:
Correction working via reach 3, but noticed that it doesnt seem to disconnect from correction via reach 3 app when turning off correction (app shows fix still etc).
To check this we connected the iphone to the the android hotspot and logged into the rs2 via ip address and could confirm that correction was indeed still on and connected (with rs3 app showing as turned off in the menu).
Interestingly rebooting and going to turn on correction in reachview 3, the ntrip info was remembered. But in reach view 2 (via iphone) it was forgotten.
In synopsis I dont think removing the sim has solved any of the issues. But we have discovered a new workflow that works this end by using the mobile hotspot on android. It doesn’t solve any of the connection issues etc and we still need to solve them. But at least we can no go and collect points. (well I can… but the colleague with the other rs2 and ios is still struggling with unreliable connection through the app, but they have a reliable ish workflow using ip address login )
Obviously this is a lot of information, I am aware I am not the most effective communicator… please ask any additional questions for clarification if required.
