Instead of using pySerial + thread it is better to use QSerialPort that is made to live with the Qt event-loop: from PyQt5 import QtCore, QtWidgets, QtSerialPort class Widget (QtWidgets.QWidget): def init (self, parentNone): super (Widget, self).init (parent) ssagele QtWidgets.QLineEdit () ndbtn QtWidgets.

(Thread modified from QSerialPort BlockingMaster example.Before you can post: click the register link above to proceed. If device is desired type ("Light"), then we format the device ID to the intended QByteArray message structure. QObject::connect(&thread, SIGNAL(timeout(QString)),įunction used to iterate through QList of devices. QObject::connect(&thread, SIGNAL(error(QString)), Setup signal-slot connections: QObject::connect(&thread, SIGNAL(sendResponse(QByteArray)),
I have tried many different examples and configurations, currently I am using the following: When I send messages to my INSTEON modem (serial), upon reading my message the device sends back a copy of my message + 0x06 (ACK Byte) followed by a status. to write the data in serial port using GUI made in qt creator.but couldnt read. I want to read data from USB port of raspberry pi and convert it to string for save it to excel file. Now, my problem – I must not have my function setup properly to send and then receive the response bytes. i want to start directly with serial port. so I delete the last topic and post new one with new details. If off, the modem would send back 0x00 in the last byte position if the device was off. The returned message indicates exactly what I would expect, that the device is on. Using Docklight, I receive the response: 02 62 1D E9 4B 05 19 00 06 02 50 20 CB CF 1E DA F7 21 00 FF I send the following message to query the state of the device: 02 62 1D E9 4B 05 19 00 This is useful to obtain the correct name of the serial port you want to use. I have tested my message using DockLight ( ). When I send messages to my INSTEON modem (serial), upon reading my message the device sends back a copy of my message + 0x06 (ACK Byte) followed by a status message. I am using the QSerialPort ( ) module to instantiate device IO support. I am sending (writing) bytes to a device via my serial port.
