System Configuration/Modem Configuration
For Application Development Using a Host Microcontroller
For modem configuration, BLE communication is realized via serial connection of a host microcontroller and RL78/G1D MCU. It is possible to flexibly respond to demands such as adding BLE to an existing application. We also have host samples for Renesas microcontrollers. This enables the shortening of the development period.
