BeagleConnect Freedom RF UART Bridge

General Discussion
1

I have two BeagleConnect Freedom boards that I’m trying to use as an RF UART bridge, but the documentation is pretty sparse on how to actually do something like this. I have a couple things that are standing in the way:

  1. My understanding is that the MSP is already flashed to be a USB-UART bridge to the CC13xx, and I can enumerate it in Ubuntu, but there doesn’t seem to be any windows drivers. Do these drivers exist?
  2. Using a TAG connect and XDS110 I flashed the RF Bridge sample software from TI onto the CC13xx, which should map the UART directly to the MSP430. When I connect to both in a serial terminal in Ubuntu, I don’t see any traffic between the two. Is the MSP doing something different than just being a bridge? The same software works fine on the C1352 Launchpad.
  3. On one of the Freedom units I want to use the UART port on MB1. This looks to go through a switch to the CC13xx, but the other option of the switch is the MSP, and is controlled by the MSP. What is the default state of this switch, and is there a way to toggle it without changing the MSP software?

I was able to answer a handfull of my questions, for anyone else who finds this:

  1. There are no windows drivers for the device
  2. The MSP was working fine
  3. After powering the system, press the boot button to switch between the header←> CC1352 and MSP←>CC1352 connections. This worked perfect with the RFUartBridge example from TI that i programed via the TAG connect, but should also work via the bootloader as long you you use sysconfig to enable the bootloader backdoor.
