Hi folks,
I am new to Node RED and MQTT, I would like to know how to use Raspberry pi UART (ttyS0) in Node Red, I mean which block I have to use it. Help me please
Kind Regards
George
The serial port node is what you need though not sure if pi has ttyS0 by default. The built in one is ttyAMA0 if enabled I thonk
Thanks for the support, I am using raspberry Pi 3 b+, in that ttyAMA0 is connected with Bluetooth BLE, so the gpio pins 14 and 15 is ttyS0.
Ah right. No probs.
