Soft serial 9k6 for debugging on free GPIO?

Hi there,

We have a prototype utilising the nRF52840 BME340 SoC module. Since we use a LoRaWAN module and a MAX3485 we used the two 840 uarts for connecting to these subsystems. But I do have some free GPIOs on the prototype PCB which I'd like to use as a console when running the project in debug mode. So I'm looking for a way to have a low-speed soft-serial taking care of logging. Any pointers, or perhaps other ways to get logging output (we are using BLE)?

Looked at some discussions on the Nordic devzone, but not a lot going for it.

Thanks,
Martijn
