Beaglebone black uart

Question

The problem is that I want to connect 4 nodemcu to beaglebone black via uart protocol, I don't know if that will work or not. I want beaglebone to work as a master computer who make the decisions depends on the data sent from sensors that connect to nodemcus.

Answer 1

It's possible, you need to attach each nodemcu to a dedicated uart, you can use 4 uarts from the following;UART0,UART1,UART2,UART4 and UART5 for twoway communication.
