3: Set Up Your mangOH Red

In this chapter, you will set up your mangOH Red to begin developing applications.

The mangOH Red kit typically includes:

(1) mangOH Red board

(1) CF3 module, pre-installed (e.g. WP76xx, WP77xx, WP8548, etc.)

(2) module covers (for 2.5 mm and 4.0 mm height modules)  One pre-installed with the CF3 module, and one for use with a CF3 module of a different height.

(1) module cover release tool

(2) micro-USB cables

(1 or 2) Ultra Wide Band antennas (taoglas FXUB63)  Second antenna included if CF3 module supports diversity.

(1) GNSS antenna (taoglas AGGBP.25B)

(1) micro-SIM card (Sierra Wireless or AT&T)

(1) Breakout board (IoT expansion card format)

(2) M2 screws for IoT card installation

Note:   The images used in this guide show the 4.0 mm cover.

3.1 Assemble Your mangOH  Quick Steps

Your mangOH kit comes partially assembled with the CF3 module and cover pre-installed.

Follow the example below to finish assembling the mangOH Red. Detailed instructions are available for each step if needed (see Assemble Your mangOH  Detailed Steps).

3.2 Assemble Your mangOH  Detailed Steps

The following steps match and provide more detail for those shown in Assemble Your mangOH  Quick Steps.

1.Verify the SW401 dipswitch pins are set correctly:

a.Remove the protective film from the dipswitches:

b.Make sure the dipswitches are set as follows:

·ON  1,3,5,8

·OFF  2,4,6,7

For switch details (not needed for this tutorial), see Dipswitch Settings.

2.Insert a micro-SIM in the slot on the bottom side of the mangOH Red. (Either the micro-SIM included with the kit, or one that has been activated by another mobile network provider.)

Note:   If you do not have an activated micro-SIM, you can continue the tutorial, but will not be able to complete Register On Mobile Network and Connect to the IoT Cloud.

3.Attach the main antenna, the GNSS antenna, and (for WP76xx modules) the diversity antenna.

Tip:   If you have trouble connecting an antenna, make sure it is positioned directly on the connector and push straight down. The antenna will not connect at an angle.

4.Move the power select jumper onto the pins closest to the battery connector to select the CF3 USB connector. (In this guide, power is supplied from the dev machine’s USB port to this connector when you connect it in a later step.)

Note:   The mangOH Red has two USB connectors:
   • CF3 USB is used for SSH connections, AT commands, and firmware downloads.
   • CONSOLE_USB is a serial connection used to access the module’s console for diagnostic purposes.

Note:   OPTIONALLY, if you want to be able to display the CF3 module’s console messages (diagnostic messages) and have two available USB ports on your dev machine, follow the instructions in Console Access . This is NOT a required step for this tutorial.

5.Power up the mangOH Red:

a.Use a micro-USB cable to connect the CF3 USB connector to a USB port on the dev machine.

When the mangOH Red is powered, the Power LED turns solid green.

Tip:   If the Power LED does not turn on:
• Make sure the cable is securely connected to the correct USB port (as shown in the image).
• Make sure the jumper block is on the correct pins (as shown in the image).

Note:   For future reference, the mangOH Red’s power supply (USB port on your dev machine, or an AC adapter) connects to the board via either USB connector  CF3 USB or CONSOLE USB (depending on the jumper position on the power header). If an AC adapter is connected to CF3 USB, SSH / AT connections are not possible; if it is connected to CONSOLE USB, serial USB connections are not possible.

6.On the dev machine, open a terminal window.

7.Make sure the modemmanager package is removed from your system (this package causes problems with mangOH Red if it is not removed)

$ sudo apt-get remove -y modemmanager 

8.Wait 10-15 seconds for the mangOH Red to enumerate.

9.Test the CF3_USB connection:

$ ping 192.168.2.2 

You should receive ping responses. Press Ctrl+C to cancel the ping request and return to the command prompt.
