I have the Ardusimple simpleRTK2B V1 board x2 in base rover configuration
LR XBee Radio
I would like to know how to get both XBee Modules working at the same time. I would like to use UART1 and UART2 for the modules.
I can get the LR Radio working in UART2 and the Bluetooth radio working in UART2 but cant get anything working in UART1 via the XBee Shield
Attached are pictures of how I have the shield wired. In the picture of the side of the assembled boards I don’t have the second and 4th pins starting from the left connected between the simpleRTK2B and the shield. Power is run from simpleRTK2B to the 4th pin of the shield via a header that is visible just to the right of the red wire.
Please provide instruction on how to how to configure the Bluetooth to be used as a wireless link to an android device providing GPS coordinates and the LR Radio to receive RTCM3 Data from the base. Specifically wiring and configuration settings.
Hi beatified, note that if you are using V1 in combination with the Shield for Second XBee socket, you need to power via USB the Shield. If you don’t want to use the USB, you have to manually do 2 things:
- Power the shield via 5V IN
- Enable IOREF on the simpleRTK2B with 3.3V
Can you please be more specific because I almost fried the GPS board by trying to do as you said. It heated up and USB wasn’t recognized. Luckily I unplugged it quickly and everything still works. Please be more specific, as I apparently didn’t understand what you were saying. I already have the 5 volts connected to the shield and it powers up the Bluetooth module just fine. I just don’t seem to have a data connection being made.
Please be specific about what physical connections should be made and what settings need to be configured in U-Center.
I just tried with boards that i had here on the table. You only need to connect 5V_OUT from simpleRTK2B to 5V IN from the shield. And the shield works.
Your board got hot because you probably connected 5V_OUT to IOREF and the shield only supports 3.3V IOREF, my mistake for not telling you this. But I just noticed IOREF is enabled automatically when you supply the shield, so i correct the comment from above, you don’t need to connect IOREF.
