It is a 2-way serial terminal, with datalogging. Here is the code for the sms : include < SoftwareSerial. Sending SMS is quite easy, you just need to write some AT commands and write the message you wanna send and hit the Cntrl + Z and it will be sent. Note: to you use my eRCaGuy_PyTerm Python serial terminal, first set all your serial parameters inside the user_config.py file, then run python3 serial_terminal.py to run the program. Hi, I have a classical SIM900 board, I can place call, it works well, but for whatever reason, I cannot read the incoming sms.

Sierra Wireless AirCard Watcher Help for Mac OS X Sierra Wireless AirCard. I use a 2nd UART like this all the time as a trick to allow me to read the data from the Arduino into one Serial Monitor in one instance of the Arduino IDE so I can see the numbers, and I use the external CP2101 USB adapter to read the same exact data from the Arduino into the Serial Plotter of another instance of the Arduino IDE so I can see the live, plotted graphs! SMS Application Note 0 Document Title: SIM5360 SMS Application Note Version. Two serial interfaces to the same pins on the Arduino: one does Tx/Rx to/from the Arduino, while the other does only Rx to read from the Arduino. Now, use screen, or my crude datalogging Python serial terminal I wrote here (eRCaGuy_PyTerm), or a 2nd instance of the Arduino IDE with the Serial Monitor, or any other serial terminal for that matter, to read from the CP2102 while the Arduino's built-in USB adapter does code uploading. Do NOT plug in the CP2102 Tx to anything. Plug it in: Arduino CP2102 USB 6-pin UARTĭone.
Let this 2nd, external UART handle READ-ONLY from the Arduino! Let the main USB serial interface handle code uploads to the Arduino. Buy a CP2102 6-pin serial UART USB adapter for < $2 on Ebay, or for < $10 on Amazon, to provide a second serial interface to the same Arduino (both connected to the same hardware UART built in to the Arduino's ATmega328 mcu). But, sometimes, the $50000 software problem can be solved with the $2 hardware solution. Virtually all hardware problems can be solved with software. At start delete all sms from sim memory Enable new message alerts using AT+CNMI command Use Interrupt based serial communication and make use of a ring buffer to store all in-coming data Whenever you will get a new message the modem will send an alert to the controller.

Other pointers on how to solve the issue are appreciated! (using screen, socat and others) but none of them deals with the question how to not block the port.
