Hello Arshad,

To launch IA, please read Operating Manual (https://marvelmind.com/pics/marvelmind_ ... manual.pdf - Starting up the system - IA) very carefully. You have to build the map by yourself.

Hello :) - Maybe you pushed "hide" button on the table of distances. Just press "show" button in the corner where table of distances should be - Or you just have no beacons in submap or something like that. Try to relaunch the Dashboard, Erase map, build map again - Install Dashb...

Re: Radio packet loss

Hello, - How far is modem from the beacons? It must not be too close - not closer than 1-2m. If you have to keep it close, then keep antenna on the modem, but remove on the close beacon.

Radio packet loss

See section 1.1.2 of the protocol: https://marvelmind.com/pics/marvelmind_beacon_interfaces.pdf Also, even in low resolution mode the expected sequence is 0x...
