Avnet Silica Liberty board is designed to evaluate BlueTooth Low Energy performance. The main processor is a Renesas R5F100EGANA. The board is also equiped with one ML7105 Lapis BLE module, one KXTJ2-1009 Kionix Accelerometer, one BD1020HFV Rohm Temperature sensor and one SMLP34RGB1W Rohm RGB led.

Using a TTL-USB converter connected with UART_TX_OUT signal of 6 pins header and a Terminal SW on the PC (such as HyperTerminal) it’s possible to see a “dump” of all data ‘send to’ and ‘received from’ ML7105 module.

BLE_lapis FW project is based on VSSPP_ML610QXXX_Ver0_094_beta firmware revision developed for Lapis PEXL7105_WSN kit and adapted for Avnet Silica Liberty Board. It is adapted for VSP application; no test has been made for VSSPP application.
