Please could someone suggest a quick fix for this. When I run the program as root (sudo) the NCS2 and OpenVINO will not work, but I can access serial (it seems) however, I am back to the beginning, when data is sent to the ESP8266, nothing comes through to the UP2. 2 serial ports detected, the first port (/dev/tts/0) is brought out on a 4 pin header labeled J1, located near a corner of the PCB. Now I have permissions issues again, the changes here changed the group from dialout to tty and owner root, I have added my user to both root and tty and I still get permissions issues. Re: detecting Rx and VCC pins on a serial port. I am unable to receive this data on the UP2.Īfter trying to resolve myself I have followed: ![]() When the ESP receives data from an MQTT broker it prints the data to serial. I have an ESP8266 12f connected to 5v (also tried 3.3) of the board and rx tx. First of all I had permissions issue to connect to ttyS4 (due to NCS2/OpenVINO not able to be run with sudo) so I added my user to dialout group, this issue was resolved. ![]() Be sure that the cable is going into the port. I been trying to receive data from rx and tx, something I have never had any issues with on any other board. For the sake of simplicity, connect the RX port of your Serial Adapter to 2S (top) and TX port to 2T (bottom).
