NOTE 1: The “Over The Air Activation” (OTAA) mode uses a JOIN phase before being able to transmit on the network. This mode uses the APP_ EUI (S214 and S215) and APP_KEY (S216 to S219) codes during this phase to create the keys for network communication.

Once this phase is completed, the codes APP_sKEY, NWK_sKEY and DEVICE ADDRESS will be present in the corresponding registers. A new JOIN phase is started every time the device exits Command mode, a reset is performed, or the device is turned on.

Codes:

The “Activation by personalization” (ABP) mode has no JOIN phase; it transmits directly on the network using the codes NWK_sKEY (S222 to S225), APP_sKEY (S226 to S229) and DEVICE ADDRESS (S281) to communicate.

Codes:

1.5 Coherency check

A configuration coherency check is made at the time of the backup. Cases where backups are refused because considered as inconsistent:

Cases refused Note
Sensor, High threshold < Sensor low threshold Aggregate peak unevaluable
peak delta > observation windows Aggregate peak unevaluable
Alarm settings inconsistencyHigh threshold + hysteresis < low threshold + hysteresis NOT SUPPORTED

2. RADIO PROTOCOL

Data with size greater than 1 byte will be transmitted MSB first. In LoRaWAN, frames are sent on port 1. Reminder: Lora Wan 868, max uplink and downlink payload is 51 bytes

2.1 Status byte

All frames sent by the product contain a status byte. Its format is identical for all IoT Adeunis products.

| --- | --- | --- | --- | --- | --- | --- |

The status byte provides two bits reserved for a specific use of each product (AppFlag1 and AppFlag2). For this product:

2.2 Uplink Frame format

2.2.1 SMART DELTA P configuration (0x10)

This frame is sent following the reception of a frame with code 0x01, or at the start of the product.

| --- | --- | --- |

| --- | --- | --- |

2.2.2 Digital inputs/outputs configuration (0x1F)

If one of the digital inputs/outputs is active, the frame 0x1F is sent at the start of the product.

| --- | --- | --- |

2.2.3 Network configuration (0x20)

This frame is sent following the reception of a frame with code 0x02, or at the start of the product.
