Arch GPRS is an mbed enabled development board that houses a cellular networking module along with a microcontroller. It is similar to the Seeeduino Arch in that it also uses the LPC11U24 Microcontroller. With the Arch GPRS, you can use the mbed C/C++ SDK, libraries and optimizing online development tools to rapidly build your prototype. The cellular networking module on the Arch GPRS is based on the EG-10 GPRS modem. With this, data collection functions can be performed easily using the 2G GSM based cellular network. Arch GPRS has a standard Arduino interface as well as Grove connectors on board. It’s convenient to connect existing Shields and Grove products to Arch GPRS. You can even connect a solar panel directly to the board to allow for the battery to charge from it. A low-power design guarantees easy charging and long hour operations when outdoors.

Yellow Area is very similar in fashion to an Arduino board, and in fact it is used as such with our Shield board. Its pin destribution is almost the same as Seeeduino Arch(D11 and D13 are swaped), so you can click here to observe each pin. The above picture is the front view of Arch GPRS, Microcontroller LPC11U24 in back has not been marked out.


Insert a SIM card into SIM Socket of Arch GPRS, you can dial a phone number or send messages. Now let's get started. Step one:Sign up a mbed account open, click Login or signup. If you have already registered, please click login directly. Step two:Import Program Open the link:, then click "Import this program" in the right corner while you can see the belowing picture. Now click "import" to complete the import of Arch GPRS program.

enter image description here

When the program has been imported into your account, you can see it in online development tool. enter image description here

Step three:Edit code open and change the main.cpp file from Arch GPRS program. Let's take calling up for example, you need to change "#define CALL_UP_TEST 0" into "#define CALL_UP_TEST 1", and change the paremeter of the function "gprsTest.callUp("133xxxx5949");". Step four:Add a device Click ”No device selected” in the right top corner, then click ”Add a device” in buttom left after you see the below picture. enter image description here Pop up a page as shown below. Arch GPRS is compatible with mbed LPC11U24 and Seeeduino Arch, so you can select either ”mbed LPC11U24” or Seeeduino Arch. Here we take selecting Seeeduino Arch for example. enter image description here Enter Seeeduino Arch page and click ”Add to mbed Compiler”, Now you complete successfully adding Seeeduino Arch. Return to mbed compiler and click ”No device selected”. The belowing picture appears after you click Seeeduino Arch in buttom left corner: enter image description here You can see your selected board in mbed online compiler after clicking ”Select Platform”. Step five:Compile、download Click"Compile", A "Success!" appears while mbed IDE generates a bin. You need to save bin file to your PC. Step six:Updata firmware Connect Arch GPRS's USB port to your computer using a USB Micro B cable and long press the botton, Arch GPRS will appear as a USB storage named CRP DISABLD. enter image description here Go to the CRP DISABLD. Now you need add the bin file you have gotten to CRP DISABLD device. If bin file has exists in USB device, you need to delect it and add the new bin file. Quick press Arch GPRS's button and wait a moment, you will hear Arch GPRS calling you. ARCH GPRS With Xively enter image description here Xively is an on-line database service allowing developers to connect sensor-derived data (e.g. energy and environment data from objects, devices & buildings) to the Web and to build their own applications based on that data. By using ARCH GPRS we can easily realize this. Step one:Sign up a Xively account open, click Login or signup. If you have already registered, please click login directly. Step two:Add your own device and Channels you can create device and add channels as what you want.If you do not know how to do ,you can visit Step three:Import program Open the link:, then click "Import this program" in the right corner while you can see the belowing picture. Now click "import" to complete the import of Arch GPRS program. Step four:Add your own information replace the FEED_ID & SENSOR_ID & XIVELY_KEY with yours,and connect your ARCH GPRS with sensor, then compile and updata firmware. Step five:check your sensor value if successful, you will see your uploaded data in your channel graph.

Note: If you use Seeeduino Arch on MAC or Linux, please read the application note --- USB ISP programming. Programming Seeeduino Arch on Windows, Linux or Mac

Seeeduino Arch doesn't have an mbed interface. It uses USB In-System-Programming(ISP) to upgrade the firmware. To enter the USB ISP mode, connect the Arch with your computer and long press its button, and then a disk named "CRP DISABLD" will appear. on windows delete firmware.bin in the "CRP DISABLD" disk. copy a new firmware into the disk. on linux if the disk is not mounted, mount the disk at {mnt_dir} dd if={new_firmware.bin} of={mnt_dir}/firmware.bin conv=notrunc on mac you'll need to use Terminal to run the following script to copy you're .bin file to your Arch dd if={new_firmare.bin} of=/Volumes/CRP\ DISABLD/firmware.bin conv=notrunc If you're so inclined, you can also create an Automator application to support drag-and-drop of the file to your board. Just create a "Run Shell Script" with the following command: dd if=$* of=/Volumes/CRP\ DISABLD/firmware.bin conv=notrunc Quick press the button to run the new firmware.
