Hi there, I got the Sparkfun RTK express plus kit this week, and am having problem pairing it with my new google pixel andriod phone. I changed the Sparkfun express to rover mode with BLE bluetooth, and eventually I see the tiny display will show the bluetooth icon after fiddling around the bluetooth configuration on the andriod phone. However app like SW Map cannot connect with it. If I select GNSS Status, it’s just show blank. What’s going on? Can someone from Sparkfun please help? I had high hope to make good use of it, but disappointed with the problem before I could even use it.
I don’t have one of these so I’m not terribly familiar with configuration.
Is there a SPP bluetooth mode you can select rather than BLE? Some software doesn’t play nicely with BLE.
If I switch to SPP mode, I never see the Bluetooth icon on the RTK express screen even though my android says it is paired. What’s the next step?
I am literally having the same exact issue. I just received the RTK Surveying kit yesterday 8/4/23. I have attempted to connect the receiver to an Android, Iphone, Macbook and Windows Laptop with no success. The reciever is recognized and showing up on the bluetooth devices lists but cannot successfully pair with any of these devices. The blue light continues to blink despite any attempts to pair/connect. Just like yourself I am very dissapointed and frustrated with this problem. I feel like my time and money has been wasted since this issue was right out of the box. I was planning on using the GPS for a construction layout staking on a house that I am building. I will now have to push out the grader since he cannot grade the building pad /driveway without stakes.
Try the steps here https://docs.sparkfun.com/SparkFun_RTK_ … bluetooth/ and if it’s still giving issues, it might help to attempt updating the firmware https://docs.sparkfun.com/SparkFun_RTK_ … re_update/
If neither of those get it working contact the seller for a repair (if purchased from us head to www.sparkfun.com/returns)
Thanks for the response, I was able to upgrade the fw to ver 3.6 and the express plus Bluetooth change to SPP mode made it to pair with my google pixel 6 successfully via SW Map app.
Resolved for me. My solution was changing the NMEA connection, and Bluetooth broadcast settings on the circuit board/mother board. The bluetooth broadcast toggle was on RTCM from the factory. I made sure that both toggles were fully upward, and was able to successfully pair in fieldgenius.
This is really bad. I updated my Pixel 6 to Android 14, and now bluetooth SPP mode no longer pair with the Sparfun Express RTK anymore. I managed to pair it when putting the RTK in BLE mode, however when I launch SW Map app, as soon as I select ‘Connect’ to the RTK, it quickly respond saying ‘GNSS instrument disconnected’. I have done many things on the android side by resetting Bluetooth setting and factory reset, and also factory reset of RTK. None of these steps can fix the problem. Does someone experience the same problem?
Did you ever get your connection issue resolved?
