bluetooth issues on RTK surveyor

I recently purchased the RTK surveyor. Out of the box the device will not connect to blue tooth. I have gotten it to connect to my iphone 13 mini via wifi, however there is no place to adjust the bluetooth protocol to BLE and there is no button to have the device check for firmware updates nor can I find the proper file to download on my computer and load to the device through my phone.

It is very frustrating for the provided instructions to not reflect the available settings on the device.

Do you have any other wifi or BLE-capable devices around that you could test with? (laptop, older phone, etc)

I use a $40 android go-phone as a dedicated GPS device (GPS, wifi, BT all work without a data plan), maybe this would be a decent option for you?
