I can successfully read the sensor’s data from a python script using pyserial by opening /dev/ttyAMA0, but it does not work in ardupilot (serial 5). For the navio config, I have: # Default settings for ArduPilot for Linux. # The file is sourced by systemd from arducopter.service TELEM1="-A udp:192.168.1.108:5555" TELEM5="-F /dev/ttyAMA0" # Options to pass to ArduPilot ARDUPILOT_OPTS="$TELEM1 $TELEM5" joego2124 March 31, 2022, 12:31am 2 I’ve tried other UART ports but they don’t work either liudmila.slepova (Liudmila Slepova) March 31, 2022, 8:50am 4 Hi @joego2124, Most likely, you need to reconsider the parameters in the Mission Planner configuration. Here is the post with Marc’s settings that should help you out: Navio 2 Setup for Optic Flow Sensor on UART Port Hardware Hello, I will try to help. I used a Benewake TF-Mini with a Navio2. /etc/default/arducopter settings: [Navio2_TFmini_Telem] Telem1 is wifi UDP to my computer, Telem2 is Sik radio on USB Telem3 is Range finder on UART “-F /dev/ttyAMA0” Serial settings: [Navio2_TFmini_Serial] -F is serial 5… Set protocol according to your need (32?) Benewake Range finder settings: [Navio2_TfMini_Rngfnd1] joego2124 March 31, 2022, 6:07pm 5 Hi, thank you for responding @liudmila.slepova . I have tested the Mission Planner parameters and they work with a different flight controller, but not with the Navio 2. I’ve also talked with the ardupilot devs and they said that the issue is likely that navio is not detecting the UART device. Could you please describe the process of adding a UART device to Navio 2 after connecting Rx and Tx? joego2124 March 31, 2022, 8:16pm 6 I was able to get the sensor data to be read by ardupilot, but only after restarting arducopter by using: sudo systemctl restart arducopter and then running a test python script that opened up /dev/ttyAMA0: import time import serial from struct import pack, unpack import sys from msp.multiwii import MultiWii class Sensor: def __init__(self, ser_port): self.ser = serial.Serial() self.ser.port = ser_port self.ser.baudrate = 115200 self.ser.bytesize = serial.EIGHTBITS self.ser.parity = serial.PARITY_NONE self.ser.stopbits = serial.STOPBITS_ONE self.ser.timeout = None self.ser.xonxoff = False self.ser.rtscts = False self.ser.dsrdtr = False wakeup = 2 try: self.ser.open() print("Waking u/p board on " + self.ser.port + "...") junk = self.ser.read(64) print([junk[i:i+1] for i in range(len(junk))]) # for i in range(1, wakeup): # print(wakeup - i) # time.sleep(1) except Exception as error: print("\n\nError opening " + self.ser.port + " port.\n" + str(error) + "\n\n") print("Serial Communication Initialized") opflow = Sensor("/dev/ttyAMA0") My theory is that somewhere along the arducopter start up process, navio is not opening the serial port, can someone please explain what’s going on? liudmila.slepova (Liudmila Slepova) April 5, 2022, 8:37am 7 Hi @joego2124, For connecting the device to Navio2, you need to configure the necessary parameter in /etc/default/ardu* file and then reload the configuration with sudo systemctl daemon-reload. If the autopilot was running while you were changing the settings, the restart is required for the changes to take the effect. system (system) Closed July 20, 2022, 2:49pm 9 This topic was automatically closed 100 days after the last reply.
