It is a simple IoT solution for plant life monitoring and maintenance, based on STM32NUCLEO boards and expansion modules. This branch is the post-eSAME development branch.
Dependencies: BLE_API X_NUCLEO_IDB0XA1 X_NUCLEO_IKS01A1 mbed
Fork of
BLE_GreenYourLife_STM32
by 
Green Building Team
This branch is the main continuation of the original project. You can find it here.
