SparkFun RTK Surveying Kit GNSS Receiver Not Discoverable on iPhone

GPS/GNSS

Hello,

I was directed by Joelle (marketplace coordinator) to post my problem here.

I recently purchased a SparkFun RTK Surveying Kit GNSS Receiver from Amazon and tried to pair it with my iPhone following SparkFun documentation, but nothing makes the device discoverable.

The surveyor seems to power up without issue, but it simply is not discoverable on the iPhone (both in Bluetooth settings and in any of the recommended apps).

Appreciate your help in avoiding a return!

Systems:

  • SparkFun RTK Surveying Kit GNSS Receiver: ZED-F9P Transceiver: ESP32 WROOM GNSS L1/L2 Multi-Band Antenna
  • iOS 18.5
  • iPhone 15 Pro Max

Apps Tried:

  • SW Maps
  • ArcGIS QuickCapture
  • ArcGIS Survey 123

You need to change the Bluetooth mode in the RTK Surveyor to BLE, if it isn’t already.

The easiest way is a serial connection to a computer, but there are various methods described :

Thanks for the reply. Configuration worked in wifi mode, and it was in SPP mode. Thanks for the right answer.
