ADICUP3029 BLE Connection Documentation
This is a guide with information regarding the BLE registration, data packet size, and configuration. This is will enable users to use the IoTNode smart app in applications leveraging the capabilities of ADICUP3029 board with Bluetooth connectivity.
General Description/Overview
IoTNode application permits the connection of a single board at a time to visualize data from it. However multiple sensors may be present on that board (ex. temperature, CO, acceleration). The information sent to the application is tied to the sensor id.
The ADI BLE packet description currently has three types of packets:
| Packet type | Value |
|---|---|
| Registration packet | 0x00 |
| Name packet | 0x01 |
| Data packet | 0x02 |
The packet type is specified using the packet type sensor id field.
The sensorID/packetType byte is composed of:
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
|---|---|---|---|---|---|---|---|
| SID5 | SID4 | SID3 | SID2 | SID1 | SID0 | PKT1 | PKT0 |
| Sensor ID | Packet Type |
|---|---|
| 6 bits | 2 bits |
You could have multiple sensors on a board with different ids the app shows information from one sensor at a time. It knows what information is related to which sensor by using the sensor id.
Registration Packet
| Data | Info | Size(byte) |
|---|---|---|
| pktTypeSensorId | registration packet | 1 |
| numFields | must match No. of field name packets | 1 |
| dataType | every field in the data packet must have this data type | 1 |
| sensorName | string with the name of the sensor | 17 |
| SensorID value | 6 bits |
|---|---|
| 0x00 | 0b000000 |
| to | to |
| 0x3F | 0b111111 |
| Data type value | Description | Size (bytes) |
|---|---|---|
| 1 | Byte | 1 |
| 2 | Short | 2 |
| 3 | Int | 4 |
| 4 | Long | 8 |
| 5 | Float | 4 |
| 6 | Double | 8 |
| 7 | Char | 2 |
Field Name Packet
| Data | Info | Size(byte) |
|---|---|---|
| pktTypeSensorId | registration packet | 1 |
| fieldId | index of field in data packet | 1 |
| fieldName | string with the name of the sensor | 18 |
Data Packet
| Data | Info | Size(byte) |
|---|---|---|
| pktTypeSensorId | registration packet | 1 |
| Sensor_Data1 | Represents 4 bytes float data for field 1 | 4 |
| Sensor_Data2 | Represents 4 bytes float data for field 2 | 4 |
| Sensor_Data3 | Represents 4 bytes float data for field 3 | 4 |
| Sensor_Data4 | Represents 4 bytes float data for field 4 | 4 |
