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
