When more the two bytes are written, the blcm_link_ctx_get call inside on_write in ble_nus.c fails (does not return). Two byte writes from central succeed but do not raise the BLE_NUS_EVT_RX_DATA event type though with fiddling of \r and \n in two bytes we do get BLE_NUS_EV...
ble_nus_init同时注册了nus_data_handler回调函数,当设备收到手机发过来的数据时,就会触发nus_data_handler,用户可以在nus_data_handler中对接收到的数据进行处理,本例程中nus_data_handler直接将ble收到的数据通过uart口转发出去。如果用户需要发送数据给手机,在连接成功和notify使能的情况下,直接调用ble_nus_data_se...
ble_uarts_data_handler_t data_handler //那么data_handler本身就是一个以(ble_uarts_evt_t * p_evt);为输入的回调函数的句柄,在句柄调用的地方直接输入 参数data_handler,即可调用这个函数。 定义了一个函数指针,同时这个函数指针的参数是一个结构体指针:形式就是(*p)(type * a) 。
在nRF5 SDK中BLE初始化的时候会注册一个回调函数ble_evt_handler来处理BLE连接、断开连接、更新PHY、Timeout等时候的中断事件 /*nRF5 SDK中的BLE中断事件*//**@brief Function for handling BLE events. * * @param[in] p_ble_evt Bluetooth stack event. ...

ble_nus_data_send每次成功发送数据包,都会产生一个BLE_NUS_EVT_TX_RDY事件,收到这个事件后,再去调用ble_nus_data_send,丢包的情况就不会再发生了,核心代码如下所示: if (p_evt->type == BLE_NUS_EVT_TX_RDY) { #ifdef METHOD2 err_code = ble_nus_data_send(&m_nus, m_data_array, &length,...
