I chose a different type of licensing

@Anticimex , I may have chosen the wrong option, please specify which license I need for open use and do not need to upload files?

Good afternoon,

I have assembled a sensor and an actuator on rs485. The devices work well. But I would like to find a way to pair devices with rs485 without flashing and without a gateway. To do this, the devices have a button to enable training mode. In this mode, the sensor should send a request, and the actuator should respond. the Received data is stored in the sensor's EEPROM. Tell me if there is such functionality?
