Sentrius RG1xx LoRaWAN Gateway + Wi-Fi / Ethernet + Optional LTE (US Only)

No, an RS1xx AS923 sensor will not work with an AU915 gateway because it cannot receive the downlink packets due to differing bandwidth and frequency plans used and therefore will drop off the network.

Once the RM1xx is put into deep sleep, it can wake up by detecting an external GPIO signal. GpioSetFunc can be used to configure which pin to use in order to wake up from deep sleep.

From the definition of GPIOSETFUNC (nSigNum, nFunction, nSubFunc), when the GPIO pin is configured to DIGITAL_IN (nFunction = DIGITAL_IN), nSubFunc parameter's bit 4 and 5 control when it wakes up the radio.

Bits 4, 5

0x10 When in deep sleep mode, awake when this pin is LOW
0x20 When in deep sleep mode, awake when this pin is HIGH
Else No effect in deep sleep mode

For example, the following line of code sets GPIO pin# 28 to trigger waking up RM1xx from deep sleep when it goes from HIGH to LOW. rc = GpioSetFunc(28,0x01,0x23)

Refer to GpioSetFunc defined in RM1xx BLE Central smartBASIC Extensions Guide v1.1 for more details.

Pin 41 is used to identify the type of M.2 card.

The Connector for the RG1xx Concentrator Card on the Sentrius RG1xx is a standard PCIE M.2 Key connector.
There are various suppliers for these connectors but the Sentrius Gateway uses a Kyocera, Part# 24 6411 067 401 894 E.

Generic ECAD Models can be downloaded from Mouser

End-devices do not actually make a connection with a gateway. End-devices broadcast to all gateways within range and the gateway forward packets to a network server if it can hear them. So, a gateway does not have a hard number for supporting devices and it is rather dependent on how much bandwidth a gateway can support. For example, factors such as payload size, interval of each data transmission or data rate being used can affect how much air time is consumed and therefore the gateway processes. Also environment factors should be considered.   

It's normally best to experiment with real devices in actual sites in order to figure out how many devices can transmit data without much data loss, using desired configuration/setup.

IP stands for Ingress Protection. Its a standard we use to check the sealability of a product once it is installed.

It is composed as IP## , where first digit is for dust/solid objects and the 2nd digit, is for liquids.
Here is the meaning for each numerical code:

There are a number of low cost hobbiest gateways on the market based on devices such as the Raspberry Pi, paired with a Semtech SX1272/SX1276, normally used in a LoRaWAN node. These low cost gateways often are single channel devices, operating on a single spreading factor. A single channel gateway can miss many of the LoRaWAN messages broadcast. The Laird RG1xx is an 8 channel gateway based on the industry standard Semtech SX1301/SX1257 chipset providing a scaleable solution able to receive on multiple channels/spreading factors at the same time.

LoRaWAN version: MAC V1.0.2
Regional Parameters version: PHY V1.0.2 REV B

The Sentrius M2 Card's SPI logic level is at 3.3V.
 

Yes, as long as they are operating on different networks such that AS923 sensors talk to the AS923 gateway and vice versa for AU915 devices. 

If you have normal RG1xx (non LTE version) and add Ethernet to Cellular bridging capability, you can access to RG1xx UI via port forwarding but with the following requirement

• need to forward whatever external port to internal port 443 to reach the gateway on that bridging device.
• Cellular provider allows incoming connections on that port.

This is an output from a GPS module on the RG1xx. The 1PPS is a standard output from GPS modules. Currently GPS is not supported on the RG1xx.

PIN 71 is an input to the RG191 and is the reset  for the SX1301.

SPI on RG1xx M2 is slave mode only

If your network servers is installed in Linux machine,
iptables --list shows what ports are allowed. Make sure all the intended ports are included here.

The below is an example of output on a machine that had Chirpstack installed.

The access keys used in TTN v2 are not used anymore in TTN v3 the API key is used instead. Follow the below steps to create an API Key for an application from The Things Stack Console.

1. Navigate to your application.
2. Select the API Keys section on the left menu and click the + Add API Key button.
3. Fill in the Name and select the Rights of your API key.
4. Click on the Create API Key button in order to create the API key. This will open the API key information screen.

Note: Please make sure to save your API key at this point because it will no longer be retrievable after you leave the page.

LoRaWAN 1.02 spec requires the end-devices to broadcast JoinReq message on Freq 923.2-923.4 Mhz.  The max output power is 14dBm. The end devices can only use SF10BW125 to join the network, which is DR2.
