Fixing a Bluetooth Connection
On rare occasions, Bluetooth on the phone can "crash". If after pressing the "Connect" button you are seeing the message "Failed to connect to device", use the phone's settings to turn off Bluetooth and then turn on again. Alternatively, restart the phone. If that doesn't fix things, read on...
Very occasionally, the Bluetooth pairing of a Sure-Path RTK receiver and the phone can go wrong or the Bluetooth module could become faulty. If the former is true, "un-pairing" and then "re-pairing" the device will usually fix things.
Un-pairing the device:
- In the phone settings, select "Bluetooth".
- If the device is still paired, it will be listed in "Previously connected devices". The name of a Sure-Path receiver will be in the form RTK_BASE_xxxx or RTK_ROVER_xxxx.
- To unpair, click the device and select "Forget". This will remove it from the list.
Re-pairing the device:
- Ensure the Sure-Path receiver has power.
- In the phone settings, select "Bluetooth"
- Select "Pair new device"
- When the receiver name is listed, click it.
- When prompted for a PIN, enter "1234".
- If pairing is successful, the device will briefly be "connected" and then it will disconnect but will remain in the list of "Previously connected devices" (THIS IS NORMAL!).
- Exit the phone settings and start the Sure-Path app.
- If it is the Base app, open the menu and select "Bluetooth Device", then click the newly paired receiver even if it appears to be already selected.
- If it is the Rover app, open the main menu and select "GPS & Network Settings". Scroll to the bottom and select "Bluetooth Device", then click the newly paired receiver even if it appears to be already selected.
- Close the menu and try to connect to the receiver again by clicking the "Connect" button.
