UART Forwarding/Passthrough

[blueshifting]

I have a GPS over UART to a nrf5283. For debugging the GPS, I'd like to passthrough UART from my PC to the GPS. I know the nrf5283 only has one UART. Is there a simple way to do this without creating a second UART in software?

You may need a nRF52840 since it has uart and also a usb. But if you want to stick with the nRF52832 you need to use the uart-ble bridge: PC <-- uart --> nrf52_1 <-- ble --> {your nrf52832} <-- uart --> {your GPS}. The nrf52_1 can be a cheap nRF52 breakout board that runs a simple program to connect to your nrf52 unit through BLE, and then all your subsequent commands from the PC will be "relayed" to your GPS unit.
