If I wish to configure JSN-SR04T for mode 3 (check the snapshot):
I’ve initialized this using the following:
Serial1.begin(9600, SERIAL_8N1, SENSOR_RX, SENSOR_TX);
Where SENSOR_RX and SENSOR_TX are 22 and 4.
I should send a value to 0x55 (85 in DEC) to the RX port, so I use this:
And from there, I should get a value from port TX, using this:
But it seems I can’t send anything to the shield. Does anyone has any idea on this?
Thanks in advance!
