An mbed BLE-to-Cloud Gateway using Nucleo-F429ZI+X-Nucleo-IDB05A1 or Nucleo-L476RG+X-Nucleo-IDB05A1+X-Nucleo-IDW01M1.
Information
Nucleo- F429ZI configuration requires two hardware patches:
- on Nucleo-F429ZI open SB121 and close SB122
- on X-Nucleo-IDB05A1 move R4 to R6
The BLE client searches for and connects to a MotEnv node.
