AT command for it to enter into command mode. I have encountered some which do not like reads of the response without some delay first. I want to open the port and read from it for a certain period of time. After that period of time, and then issue write commands. After a pause of several minutes, I can open my serial ports.I meant to ask you in the last reply. Thank you.I am with a problem when I trying to communicate a bluetooth device using Pyserial and AT commands. I posted my code below if someone has any hit I would appreciate. It must have registered all the files. Now, the port will reopen and the RPi will read data from it again. LED commander is a simple GUI for controlling an output pin of the Arduino. This project was made as a little tutorial/example to show the possibility of controlling an Arduino board with Python and a GTK interface. HT is a convenient tool for "sanity checking" of your computer's ports and the programs you develop to communicate. This simulator is useful for developing Python programs that will eventually communicate with Arduino hardware. The program won't have to worry about connecting hardware to the development computer until the very last step of the development process. This file definitely has problem locating the installed python and thus never lets you run it. Apparently, the port closes and the received data will be analysed. A robust server side script will read from the serial port until the Arduino declares itself ready, you need to run this or you can't do crap with serial communication.
