Abstract

Arduino implementation to read the sensor data from a explicit MiFlora devices.

Other than the implemantation from Ahmet (https://github.com/ahmetanbar/miflora-arduino) this implementation uses directly the BLE services from the Device. With the DISA command I got the problem that the HM-10 was not regognizing the MiFlora device but a lot of other BLE-Devices

Steps you need to do before

Usually a firmware Update. You NEED the "Self-Learning Functions" --> So V700 or higher
Set your HM-10 in "Master Mode": AT+ROLE1
Set your HM-10 in "Manual Connect": AT+IMME1
Set the Baudrate to 19200: AT+BAUD1

My Setup

Original arduino UNO R3
DSD Tech HM-10 Clone
MiFlora Sensor: Flower Care / Model: HHCCJCY01HHCC
CH340C - USB --> UART Converter for flashing and testing
