Kurt asked 3 weeks ago

I have a few things I’m working through. I am relatively new to all of this. I purchased a RTK2B LR in May. I had it working, but with my tablet I only had one USB port, so I used a USB hub but it could not keep up with data transfer, About a 4 second delay. Instead of using a bigger device I decided to buy a secondary shield to support Bluetooth to help with data transfer and use USB port for controller that is run on GPS. Is there another way I could have addresses this? Configuration?
I plugged the accessory shield with Xbee Bluetooth shield into my existing RTK2B shield which had headers soldered to it, but it did not power up, assuming the data is not getting to it either. Assuming there is a simple answer to this? I double checked the pin orientation and it seems to be correct. The Xbee Bluetooth was purchased after the fact so does it need to set up somehow? And what is the default PIN?

I am using the system for elevation data controlling a scraper for earthmoving, I have configured the RTK to for high precision, as high resolution elevation data is what I am after. 

any help with these issues or proper configuration would be greatly appreciated, again I’m relatively new to this, so if the answers sound simple, they probably are! 

Thanks,
Kurt

(AS) 2 devices at the same time should be possible for USB, if you are using u-center sometimes the issue is the visualization in u-center gets delayed. But it could also be too much data for the USB hub if you are using a USB 1 hub and pushing the datarate high.

I think it’s written in the bottom of the shield, if you use it together with simpleRTK2B V1 you need to power the shield externally (connect USB, or wire 5V IN).
As for the bluetooth, just make sure you have enabled NMEA at 38’400bps in the port selected in the switch of the shield. The bluetooth is pre-configured at this speed. The PIN is either 0000 or 1234, you are right the pin is not documented we will update the documentation.
