$30-250 USD

Paid on delivery
I need an ESP32 with an i2c MCP9808 sensor to send data via BLE to a Raspberry Pi 3B+. I assume it would be done with MQTT-SN but can be done anyway as long as Wifi is not used. It can be done on Arduino or Micro-Python I will need the ESP32 code and a step by step guide on configuring the Raspberry Pi. I am running NODE-RED to analyse the traffic that will be sent from the sensor.

Good Day! I have just finished project that uses MQTT over internet especially using AWS IoT. But since your project will only be over BLE and over your local network. This is very much within my skillset. I am a Embedded Systems Engineer based here in the Philippines. I have been doing microcontroller projects for the past 6 years now. Most of the time I use arduino as well. I am meticulous and make it a target that all objectives of the project is met within the time limit. I Hope to work with you soon! Cheers!
