Flash JetPack​

reServer J2032 already comes pre-flashed with JetPack out-of-the-box. But if you want to reflash the device, please follow this wiki.

Quick Start with reServer Peripheral and Module Assembly​

!!! Note: reServer J2032 will come with Jetpack 4.6.1 preinstalled on the EMMC of the Jetson Xavier NX module which means you could directly start to develop your own application with it.

Hardware Required​

You need to prepare the following hardware before getting started with reServer。

  • reServer
  • Power Adapter(provided)
  • External monitor
  • HDMI/DP cable
  • Keyboard and Mouse

Peripheral and Module Assembly​

For this part, we will introduce how to install or replace some supported hardware/module inside reServer. please skip it if the following step does not apply to your use case. You might follow the Assembly Guide Manual attached at the end of this page to access to the main board of reServer before reading this part.

LoRaWAN® Module Mini-PCIe Port Installation​

!!! Note: The following setup guide of install the LoRaWAN® Module in the Mini-PCIe port only tested with following modules WM1302-USB-US915 or WM1302-USB-868. the LoRaWAN® Module does not include.

  • Step 1. Spot the Mini-PCIe slot on the back of the carrier board and install LoRaWAN® Module.

pir

  • Step 2. Connect the antenna cable and locate the antenna mounting slot on the back of the reServer J2032 case which should have a rubber insert blocking the hole.

!!! Note: reServer J2032 does not shipped with Antenna Adapters and Antenna.

pir

  • Step 3. mod reServer J2032 to be used with LoRaWAN® module by type following command into the Terminal:
sudo -i
cd /sys/class/gpio/
echo 268 > export; echo out > gpio268/direction; echo 1 > gpio268/value
echo 495 > export; echo out > gpio495/direction; echo 0 > gpio495/value

pir

  • Step 4. check if the LoRaWAN® module is connected properly，open Terminal and type following command:

!!! Note: The following steps on enabling the LoRaWAN® module only tested and applied on the Factory Default Jetpack 4.6.1 

ls /dev/ttyACM*

You should see following output as following:

pir

OR

lsusb -t

You should see following output as following:

pir

  • Step 5. To use the LoRaWAN® Module please download the source code:

Now let's install git and download sx1302_hal(library and programs for SX1302 LoRa® Gateway) from github:

sudo apt update
sudo apt install -y git
git clone https://github.com/Lora-net/sx1302_hal

Move to sx1302_hal folder and build the program:

cd ~/sx1302_hal
make

Start to run the LoRaWAN® gateway application, here is an example of using the WM1302-USB-868 module, where the config file global_conf.json.sx1250.EU868.USB has been choosen:

cd packet_forwarder/
sudo ./lora_pkt_fwd -c global_conf.json.sx1250.EU868.USB

You should see similar output like this:

4G/5G Module Mini-PCIe Installation​

!!! Note: QC25-EUX 4G module is used with the following setup guide and the module does not included.

  • Step 1. Locate the Mini-PCIe slot on the back of the carrier board and install LoRaWAN® Module.

!!! Note: You need to insert a standard SIM card into the reServer J2032 SIM card slot to enable 4G/5G network. If you look closely, the SIM card Tray has two Layers, the Mini-PCIe port is utilisting the SIM Slot 2 as indicated in the picture below.

pir

  • Step 2. Connect the antenna cable and locate the antenna mounting slot on the back of the reServer J2032 case which should have a rubber insert blocking the hole.

!!! Note: reServer J2032 does not shipped with Antenna Adapters and Antenna.

pir

  • Step 3. mod reServer J2032 to be used with QC25-EUX 4G module by type following command into the Terminal:
sudo -i
cd /sys/class/gpio/
echo 436 > export; echo in > gpio436/direction;
export; echo in > gpio268/direction;
export; echo out > gpio393/direction; echo 1 > gpio393/value
echo 495 > export; echo out > gpio495/direction;
echo 1 > gpio495/value
echo 0 > gpio495/value
  • Step 4. check if the QC25-EUX 4G module is connected properly by power up and boot into the system, then open Terminal and type following command:

!!! Note: The following steps on enabling the QC25-EUX 4G module only tested and applied on the Factory Default Jetpack OS Version 4.6.1 

lsusb -t

You should see following output as following:

pir

  • Step 5. Enable QC25-EUX 4G module to connect to 4G network, please open Terminal and type:

Open minicom serial moniter with the 4G module plugged in

sudo apt install -y minicom
sudo minicom -D /dev/ttyUSB2 -b 115200m1

once the serial connection opened, Type in AT and press 'Enter', and you should see OK.

At the same minicom serial window please type:

AT+QCFG="usbnet"

It will return something like +QCFG: "usbnet",0, but we need that to be set to 1 (ECM mode), so enter the following command:

AT+QCFG="usbnet",1

Then enter the following command to force the modem to reboot:

AT+CFUN=1,1

Then you could reboot or wait for a while for the moudel to get internet from your sim card carrier.

Now if you type ifconfig in Terminal you should see the similar output as image shown below which you have assigned an ip address from your SIM Card mobile carrier:

4G/5G Module M.2 B-key Port Installation​

!!! Note: The M.2 B-Key on reServer J2032 support 3042/3052(USB3.2 GEN2) format supports 4G/5G Wireless Module (4G/5G Module is not included in reServer). The SIM8202G-M2 5G module is used in the following steps.

  • Step 1. Install SIM8202G-M2 Module to M.2 B-Key.

pir

  • Step 2. Connect the antenna cable to the Module.

!!! Note: reServer J2032 does not shipped with Antenna Adapters and Antenna, For using the SIM8202G-M2 5G Module to connect network you need to have Antennas attached to the module.

pir

  • Step 3. Mod reServer J2032 to be used with SIM8202G-M2 5G module on the M.2 B-Key port by type following command into the Terminal:
sudo -i

!!! Note: The following steps on enabling the SIM8202G-M2 5G module only tested and applied on the Factory Default Jetpack OS Version 4.6.1 

lsusb -t

You should see similar outputs as shown below:

pir

Step 5. Enable SIM8202G-M2 5G Module to connect to 5G network

!!! Note: You need to insert a standard SIM card into the reServer J2032 SIM card slot to enable 4G/5G network. If you look closely, the SIM card Tray has top and bottom two slots, the M.2 B-key port is utilisting the Bottom Slot.

pir

Open minicom serial moniter with the SIM8202G-M2 5G module plugged in

sudo apt install -y minicom
sudo minicom -D /dev/ttyUSB2 -b 115200m1
