The image shows the error when running the following code.
import serial #import serial pacakge from time import sleep import webbrowser import sys def GPS_Info(): global NMEA_buff global lat_in_degrees global long_in_degrees nmea_time = [] nmea_latitude = [] nmea_longitude = [] nmea_time = NMEA_buff[0] nmea_latitude = NMEA_buff[1] nmea_longitude = NMEA_buff[3] print("NMEA Time: ", nmea_time,'\n') print ("NMEA Latitude:", nmea_latitude,"NMEA Longitude:", nmea_longitude,'\n') lat = float(nmea_latitude) longi = float(nmea_longitude) lat_in_degrees = convert_to_degrees(lat) long_in_degrees = convert_to_degrees(longi) def convert_to_degrees(raw_value): decimal_value = raw_value/100.00 degrees = int(decimal_value) mm_mmmm = (decimal_value - int(decimal_value))/0.6 position = degrees + mm_mmmm position = "%.4f" %(position) return position gpgga_info = "$GPGGA," ser = serial.Serial ("/dev/ttyS0") #Open port with baud rate GPGGA_buffer = 0 NMEA_buff = 0 lat_in_degrees = 0 long_in_degrees = 0 try: while True: received_data = (str)(ser.readline()) GPGGA_data_available = received_data.find(gpgga_info) if (GPGGA_data_available>0): GPGGA_buffer = received_data.split("$GPGGA,",1)[1] NMEA_buff = (GPGGA_buffer.split(',')) GPS_Info() print("lat in degrees:", lat_in_degrees," long in degree: ", long_in_degrees, '\n') map_link = 'http://maps.google.com/?q=' + lat_in_degrees + ',' + long_in_degrees print("<<<<<<<<press ctrl+c to plot location on google maps>>>>>>\n") print("------------------------------------------------------------\n") except KeyboardInterrupt: webbrowser.open(map_link) sys.exit(0) I ran the code in raspberry pi 3 with NOOBS OS. I tried this link.
The error says.. OSError: [Errorno 16] Device or resource busy: '/dev/ttyS0' and that 'During handling the above expression another error occured' Kindly someone help me..I'm working on the project IoT based Heart rate monitoring system using Raspberry Pi3 and having only 2 days to complete the project..
