i want to connect the samb11 mr210ca board with my µC atsamd21j18a.
i have connected the board with spi sercom 3 and uart.
if i want to write the ble_device_init() in my main(), my debug port sends me a message like "Please check the power and connection / hardware connector".
in this function i become this message: ble_manager.c
/* Initialize the BLE */
static void ble_init(at_ble_init_config_t * args)
/* Initialize the platform */
DBG_LOG("Initializing BTLC1000"); // this comes
/* Init BLE device */
if(at_ble_init(args) != AT_BLE_SUCCESS)
DBG_LOG("BTLC1000 Initialization failed");
DBG_LOG("Please check the power and connection / hardware connector"); // this comes after a timeout ~ 10sec.
could someone please help me?!
