1. Introduction of Breakout M35
Breakout M35 is a product developed by AT-COM based on the features of the M35 module. Breakout M35 is designed in a compact size, SIMCARD is integrated in the circuit to help users easily research and deploy applications related to GSM / GPRS such as remote monitoring control, data collection Remotely via GPRS, SMS ... Besides, with compact size, convenient data output, Breakout M35 will bring the most modern and sophisticated design inspiration. Breakout M35 is designed with 18-pin output divided into 2 rows. Output power supply, data communication between Breakout M35 with external microcontroller, LED display Network status, UART, RTC, Audio, Speaker ...
2. The hardware connect with Breakout M35
To test the Breakout M35 user circuit should prepare the following problems:
Use a GSM antenna to connect to the RF Connector on the Breakout M35 circuit, which allows the circuit to receive GSM / GPRS waves. The Breakout M35 is designed with an outboard antenna connector that fits well into the case when it comes to product design with Breakout M35. Depending on the application, users can use GSM antennas of different sizes:
Using a Simcard of the network support 850MHz / 900MHz / 1800Mhz / 1900MHz frequency bands as Mobifone, VinaPhone, Viettel ... On the Breakout M35 circuit is designed a Simcard Holder using click to add the Simcard.
3. Breakout M35 test guide on QNavigator_V1.2 software
After completing the installation of the software, driver ... we power the L5973 Step Down circuit and press the Powerkey button to start the M35 module. When the Power up is clicked, the LED Status on the circuit will light up and after a few seconds the LED will flash and the M35 module will start scanning the network, checking the SIMCARD ...
Next, plug the USB to UART into your computer and run the QNavigator_V1.2 software on your computer. The interface and functionality of the QNavigator_V1.2 software is as follows:
To communicate with the first M35 module, we need to select the baud rate to communicate with the UART of the M35 module. Default when producing Breakout M35 in Autobauding mode.
After selecting baud rate, we choose Connect to module.
After selecting Connect to Module, Module M35 will check and display the parameters of module, Simcard such as: Manufacture ID, Firmware version, Network, SIMCARD IMSI ...
Use the SMS test tool to test the M35 module's SMS transmission and reception function.
If the message is successfully sent, it will display the following:
Use the test call tool as follows:
Users can refer to AT Command for M35 modules to configure and test many other functions of M35 module such as TCP / IP, PPP ... by referring to AT Command:
