Connecting nRF24L01 to the ESP32

nRF24L01 ESP32 GND GND VCC 3.3V CE D4 CSN D5 SCK D18 MOSI D23 MISO D19

Connecting MicroSD Module to the ESP32

To connect the SD Module I have adapted a simple Arduino example:

MicroSD Module ESP32 GND GND VCC 5V or 3.3V CS D22 SCK D18 MOSI D23 MISO D19

Server

Raspberry Pi and MQTT server

The Mosquitto MQTT server can be set on a Raspberry Pi in the network and it uses IBM's Node-Red. To configure it I have followed this tutorial.

Docker

To setup the entire server part of the ardutracker project, you need to have installed Docker with docker-compose in a x86_64 capable machine with at least 1GB of ram a single core CPU.

Move to the /ArduTrackerServer/ directory and type in a terminal docker-compose up -d. After that, you can stop all the services using docker-compose down, always in the same directory.
