Hi there,
I am having this same (similar) issue and would appreciate any insight. Since i have updated the firmware on my trimble R1 i can no successfully longer connect it to the iphone 6 (ios 12.3.1). The trimble is updated to firmware 5.41 as of June 23, 2019.
The trimble will show up in the bluetooth, and will successfully connect.
When i open my gnss status utility app to find satellites i can again successfully see that i have an established bluetooth connection to the R1. I cannot, however, connect to any satellites and my phone appears to be using the phone GPS instead of the trimble - despite being connected to the trimble via bluetooth.
The trimble additionally continues to flash with the yellow light, indicating it has not found satellites.
This is what i see in GNSS status:
Any help to get this back up and running will be greatly appreciated!
Cheers,
Jennie
