Just started using QField and trying to improve accuracy. Is there anyway to connect a Columbus P-7 pro? I added it as a BLE device, but then it continues to get an error. Can I connect it directly and use TCP? Have been looking on the forum and can’t find the information. ---

Hello @Mpg66170 ! I don’t have an iPhone, but according to [this page of the documentation](https://docs.qfield.org/ro/how-to/navigation-and-positioning/gnss/#using-an-external-gnss-receiver), there should be support in iOS for a TCP connection. When you press the ‘add’ button below the `Positioning Device in Use` dropdown, there is the option to create a new `TCP (NMEA)` connection. What error do you get when using it with a BLE connection? I seem to remember from other topics on this thread that on iOS the only supported type of bluetooth connection is BLE, and not “classic” bluetooth. ---

And not certain about the port? I was trying to use Bluetooth Maybe I should just try the TCP and see what happens. ---

Hi hi, currently it is not possible to connect an external GNSS device via bluetooth with IOS. This remains an obstacle with using IOS for now, which we are trying to solve. @Mathieu_Pellerin will know more.
