Reyax Rylr993 Lorawan Transceiver Module User Guide (+ PDF)

The RYLR993 is a module that can be used for data transmission
through the Helium Network, which is a globally distributed network
of hotspots that creates public long-range.

What is Helium Network

Helium Network is a globally distributed network of hotspots
that creates public long-range.

To check the nearby hotspot, please refer to https://explorer.helium.com/.

How to apply Helium Network service

To use Helium network service, you must pay to purchase DC (DATA
CREDITS) for data transmission. Please refer to the website link
below for applying Helium Network service: https://docs.helium.com/use-the-network/console/quickstart.

After applying, you can create a Device in console environment
to get Device EUI, App EUI and App Key. These three data are the
account ID and password that used by the RYLR993 module to connect
to the Helium Network. You can go through https://console.helium.com/ to
see the information. Usually, it will take a few hours for the sync
after you create the Device.

Instruction of how to use RYLR993 and Helium Network for data
transmission

The following describes the simple usage process. For advanced
usage commands, please refer to the RYLR993 AT Command file.

Boot Information

The following strings will be occurred after you Boot or
RESET:

BAND:US915
`Stands for the current frequency Band
+READY

Set Frequency Band

After sending AT+BAND=0, RYLR993 will response as below:

BAND:AS923
OK

Test the response of RYLR993

After sending AT, RYLR993 will response as below:

Set DEUI

After sending AT+DEUI=60:81:F9:AF:21:68:5C:5F, RYLR993 will
response as below:

Set APPEUI

After sending AT+APPEUI=60:81:F9:6B:CA:11:C0:17, RYLR993 will
response as below:

Set NWKKEY

Because Helium Network is an APP itself, therefore the NWKKEY in
RYLR993 is, after APPKEY send
AT+NWKKEY=FA:74:AF:C5:95:7A:B7:BF:52:E3:6F:AE:EA:C1:BA:D5:, RYLR993
will response as below:

Log in to Helium Network

After sending AT+JOIN=1, RYLR993 will response as below:

OK
+EVT:JOINED
`Successfully Login to Helium Network
+EVT:RX_1, DR 0, RSSI -19, SNR 8
`The quality of the signal status

Sending data to Helium Network

After sending AT+SEND=1:1:31323334, RYLR993 will response as
below:

OK
+EVT:SEND_CONFIRMED
`Confirmation of sending data successfully
+EVT:RX_1, DR 2, RSSI -18, SNR 7
`The payload field are the data that has been uploaded
successfully, and the format is BASE64

Receive the data transmitted from Helium Network to
RYLR993

As the figure shown below, 12345678 in Text format can be
transferred to RYLR993.

Due to Helium Network can only download the data when RYLR993 is
uploading the data, therefore it is needed to send
AT+SEND=1:1:31323334:, and RYLR993 will response as below:

OK +EVT:SEND_CONFIRMED +EVT:1:08:3132333435363738 +EVT:RX_1, DR
2, RSSI -28, SNR 7
`Confirmation of sending data successfully

Helium Network can be integrated with other service

Helium Network can also be integrated with other network
protocols and services.

1. What is LoRaWAN®?
The LoRaWAN® specification is a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated `things’ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-toend security, mobility and localization services. For more details, please refer to https://loraalliance.org/
2. What is Helium Network
2.1 Helium Network is a globally distributed network of hotspots that creates public long-range
wireless coverage for LoRaWAN® IoT devices. Helium blockchain network is an open-source public blockchain that create a decentralized wireless networks. For more details, please refer to https://www.helium.com/
