Hayes AT Commands (for RAK811 LoRaWAN) with Node-RED using flow (context) functions and variables
Hi, I would like to share my flow to manage AT sequences (array of AT commands) for RAK811 breakout board. The RAK811 breakout is a 3.3V LoRaWAN board. It can be connected with a FTDI to a USB port of a PC or a Raspberry Pi SBC. It can also be connected to Rpi UART (Rx/Tx) GPIO (15/14). The flow is able to manage an array of expected AT answers with an expected timeout for each answer. Have fun...
