QUESTION: How to read a second serial line

General
1

I need to connect a Feather 32u4 LoRa wireless node to an ESP8266 running Mongoose so I can relay the data onto WiFi.

I’ve looked at the Mongoose UART API (https://mongoose-os.com/docs/mongoose-os/api/core/mgos_uart.h.md). There is no Rx facility on the ESP8266’s second UART. In Arduino, I can use SoftwareSerial to synthesis an Rx pin. But there’s nothing like that here (is there?).

I can’t figure out if you can swap the terminal UART or not and, basically, I’m confused.

How would you get data off a non-wirleless device and onto a Mongoose device?

Thanks!

You can try to set debug.stderr_uart=1 and debug.stdout_uart=1 to move the serial console to UART1.
