你好!
想用两个585互传信息，测试了好久DSPS例程，没有找到办法。我用的是dsps_device_dma和dsps_host_dma。能否帮我下以下问题：
1）device代码在什么地方(用什么函数)读取host传来的数据? device代码在什么地方(用什么函数)传数据给host?
谢谢了
你好，
主机- >设备,设备接收数据,从底层到上层,数据的流向是:
BLE STACK-> GATTC_WRITE_REQ_IND -> gattc_write_req_ind_handler --> sps_server_data_receive -> SPS_SERVER_DATA_WRITE_IND -> user_sps_server_data_write_ind_handler
设备-> host，device 发送数据，从上层到底层，数据流向是：
user_send_ble_data -> SPS_SERVER_DATA_TX_REQ -> sps_server_data_tx_req_handler -> sps_server_send_data -> GATTC_SEND_EVT_CMD (GATTC_NOTIFY) -> BLE STACK
