Bluetooth 5.0 network - Arduino - ESP32 -- 2

Be sure you understand all details.

You must have ESP32 devices for testing ! At least 2 devices ESP32 !!!!


We have 3 tasks:

Task 1 - - - - - - - - - -

Creating a full Bluetooth network for ESP32. (Bluetooth 5.0. ...distance range is required for more than 100 meters). We will test it outdoor.

Network must have at least "Coordinator" and "End node" roles. Repeater role can also be configurate if you can (repeater is not compulsory).

We will use internal BLE circuit of ESP32.

My network will have more than 10 devices.

If this task is not OK we will stop here and cancel the project.

Task 2 - - - - - - - - - -

Integration of some sensor (SHT31 or PIR detector) in order to test the network devices.

Implement Remote rele activation using GPIO25 in End node (EPS32). Comand for activation will be provided from Coordinator.

//I2C pins

#define I2C_SDA_2 33

#define I2C_SCL_2 32

//SDCARD pins (SPI pins)

#define SPI_CLK 18

#define SPI_MISO 19

#define SPI_MOSI 23

#define SPI_SS 5

Optional: Hibernate to be integrated in the end node device.

I can help you with this task.

Task 3 - - - - - - - - - -

If data can not be sent to coordinator, due to coordinator is down, save the data on SD card (unsend,txt file) and send it when coordinator is on. (we must receive all data)

Save the daily data to SDcard in file using " [login to view URL] " name (for example: [login to view URL]). Only one file per day.

Frecquency to read and save parameters on file: every xx seconds. Frecquency parameter must be defined.

I can help you with this task.
