Reach RS2 and FG for Android

Sure, I’ll be as detailed as possible and I’ll start from a clean state (all previous pairings ‘forgotten’):

Method one (try to pair from within FG)

  1. Power up RS2, Samsung Galaxy Tab A (2017), and computer
  2. RS2 connects to local wireless (same as tablet and computer)
  3. Computer logs onto ReachView v2.20.7 via local network (for configuring RS2 and monitoring RS2 side)
  4. Set RTK Settings: Kinematic, EMA 15 degrees, SNR-M 35, GNSS selected: GPS, GLONASS, GALILEO; Update Rate: 1Hz
  5. Set Correction Input: NTRIP to Florida Precise Reference Network (Station KREG - RTCM 3.1 MSM4) All confirmed as working and allowing RS2 to gain FIX. Approx tested baseline is 15km)
  6. Position output 1: Turn On, Set to BT, Format NMEA (states send error (111) - expected because not yet paired)
  7. Base mode: off
  8. Logging: on
  9. Mobile Data: On, connected to TING 3G for NTRIP streaming
  10. WIFI: On, connected to local network (or hotspot if away)
  11. Bluetooth: Turn on, Turn on always discoverable with PIN code [123456], states no paired devices, shows several discoverable devices including Samsung Galaxy Tab A and computer. (in this method I try to pair from FG menu only)
  12. Launch FG android
  13. Set new project up: Name: test, Distance: meter, Angle: Degrees, Coordinate: FL83-E (Florida state plane, meter), Vertical: ellipsoidal WGS84
  14. select instrument: Add profile; select GNSS rover; Make = NMEA, Model = Basic, Profile name NMEA-Basic, select create
  15. click set up communication, choose Bluetooth, search for device, select reach, select connect. FG states connecting to instrument. [NOTE I am not asked to enter a passcode or anything]. Unit connects.
  16. set up corrections: no RTK [handled by RS2 internally]
  17. set up antenna height [2.134m]
  18. use default
  19. FG android GNSS Rover Profile page shows:
    connection, satellites [12], PDOP [2.5], click done, back
  20. FGA shows location on map, and position text, option to record point ,etc.
  21. in less than 20 seconds, position and coordinates disappear without message. Righthand side of FGA changes to: select instrument or reconnect. Selecting reconnect connects again for less than 20s. And reverts to Select instrument/reconnect. Every time I hit reconnect, it connects, shows the position/option to record. And disconnects within 20s. Doesn’t matter how close unit tablet are to each other.
  22. on reachview position output page. when connected it shows: connected to local host, within 20s, it shows send error (32), then send error (111).

method 2 (pair devices first)
steps 1-11 above are the same.
12b) From Reachview Bluetooth tab select Galaxy Tab A from discoverable devices
13b) Tablet receives pairing message. Select OK. Now tablet and reachview show that they are paired.
14b) Launch FG android (new launch after previously closing down)
15b) open project, select instrument, add profile, gnss rover, make = NMEA, model = basic, click create
16b) click set up communication, Bluetooth, search.
17b) select reach
18b) set up profile as before
19b) same result, disconnects within 20s.

Random note: When connecting the RS2 to my computer, the prompt asks if the PIN on the device matching the one displayed. Every time, it shows a pin that is different than 123456. haven’t been in a situation where I’ve been asked to input a pin and needed to use 123456.

other note: I have two RS2 units. Same behavior on both.

You’re not alone @Africawaterdoc I’ve been testing FGA over the weekend on a Samsung Galaxy Tab Active 2 with the exact same disconnect issue with Bluetooth.

I have tried using the NMEA and Reach RS instrument settings within FGA, but the behaviour is the same - disconnects after approx 20 seconds, which make setup, let alone use, of FGA with an RS2 basically impossible.

I will also email MicroSurvey support to see what they say.

I spoke to Michael Bachinski from MicroSurvey the other week about this.

Turns out the ‘infinite‘ Bluetooth disconnect issue when using FGA (at least on Samsung tablets) and connecting to a Reach RS2 are known to MicroSurvey. They are working to resolve it.

To expensive!

If anyone here hasn’t seen my other posts, FG for Android v1.2, which will be released very soon, has the connection fixed for the Emlid RS2 units, and we have been able to get them working with both RTK and NTRIP connections. Local Transformations will also be included in the release and more…

Now that’s what I’m excited about! ; )
