SoftwareSerial for STM32WLE5

[keniihuang99]

Hi Sir,
I have a project use STM32WLE5 and need 4 UART for :

1. read sensor from RS485
2. read GPS
3. communicate to the other module via UART
4. send debug message to PC

it seems STM32WLE5 could provide two hardware Serial, could I use SoftwareSerial for the other two UART?

Thanks in advance for your help.

Hi @keniihuang99
Honestly I do not recommend the SoftwareSerial as it consume lot of ressources.
You can try it and if it is fine for you then use it.
