Hi – I have two simpleRTK2Bs with Survey GNSS antennas. I use one as base station via a laptop with SNIPE and one as rover. When I use the rover via USB on either a Windows Laptop or an Android Tablet, everything works fine.
However, I also have an XBee Bluetooth unit (AS-XBEE-BT-2.4-INT-00) that I was planning to use for the rover. Unfortunately I cannot make the XBee Bluetooth work on neither the Windows Laptop nor the Android Tablet. I have 4 blue LEDs: i) LED2 (Power) = Blue fixed, ii) GPS > XBEE = Blue long flash, iii) GPS Fix = Blue short flash, iv) No RTK = Blue fixed. I take ii) to indicate that the problem is not related to comms. between the simpleRTK2B and the XBee unit.
The XBee appears as RTK_GNSS_255 on the list of selectable units on both the Android tablet and the Laptop. Prior to connection, LED 1 on the XBee flashes RED rapidly. I can then proceed to connect using the code 1234. Upon connection LED 1 goes dark, the unit appears as connected on the Android Tablet (alternatively on the PC – not both at the same time). Then, within ca 2 sec the tablet is disconnected and LED 1 starts flashing slowly RED. LED 2 on the XBee remains dark in all phases.
Any suggestions on how I may make it work are very welcome.
