multirole example send data
Posted by本杰明Du135分 12 repliesHi Dialog,
In short, my question is how to send data to slaves inMultiroleexample.
让我解释一下我的问题：
I useDA14531-DA14585 586_Multirole_Example to connect with multi slaves (I useble_app_profile示例），我可以连接多个从站和主设备（Multirole) can receive data from slaves,but I don't know how to send data to slave, I use iPad to connect the slave(ble_app_profile示例），从而可以接收数据。
I tested the following inuser_catch_rest_hndlCallback, I hope if there is data received, then I will send data to slave, but I can received data from slave, while slave can not receive data.
struct gattc_write_cmd *wr_char = KE_MSG_ALLOC_DYN(GATTC_WRITE_CMD,
dest_id, src_id,
gattc_write_cmd, sizeof(struct gattc_write_cmd));
// Offset
wr_char->offset = 0x0000;
// cursor always 0
wr_char->cursor = 0x0000;
// Write Type
wr_char->operation = GATTC_WRITE;
//特征值属性句柄
WR_CHAR->手柄= 1;
// Value Length
wr_char->length = 3;
// Auto Execute
wr_char->auto_execute = true;
// Value
int8_t AA[2];
AA[0]=9;
AA[1]=5;
memcpy(&wr_char->value[0],AA, 2);
// Send the message
ke_msg_send(wr_char);
Thanks

嗨对话框，
Thanks so much for your quick answer.
I finduser_ble_gatt_write()与上面使用的功能类似，无论如何，我测试了不同参数的函数，但仍然无法在从站中接收数据。
您是否可以帮助举例说明如何使用此功能的参数？从图片显示，如果函数可以发送相同的数据，则从闪烁从闪烁的数据显示，我认为它可以是一个非常好的起点，我将能够使用这个功能。
再次感谢.
本杰明

Hi Benjamin,
为延迟道歉。快速问题：您希望从间隙中央设备写入哪种服务？是定制服务吗？
Can you please share how the user_ble_gatt_write() is called?
Thanks, PM_Dialog

嗨对话框，
非常感谢您的回复。
I calleduser_ble_gatt_write()在功能中user_catch_rest_hndl().
following is part of the code I used to do the calling.
570
571案例gattc_event_ind：
572 {
573
574 //following add by Benjamin
575 INT8_T AA [2];
576 AA[0]=9;
577 AA[1]=5;
578
579 user_ble_gatt_write（gattc_write_cmd，conn_idx，svc1_idx_led_state_val，aa，sizeof（aa））;
580
581
582 //following two lines output received data.
583结构gattc_event_ind const * msg_param =（struct gattc_event_ind const *）（param）;
584 arch_printf("<%d>\t",msg_param->value[0]);
585 //above added by Benjamin

Hi Dialog,
What's the difference between different services？ do you mean in custom service I can not do the calling?
My question is if I can do the right calling and the slave can receive, anywhere is OK.
Thanks

Hi BenjaminDu,
请从中央实施SW示例检查Handle_svc_ind（）。当收到GattC_SDP_SVC_ind时，Handle_svc_ind（con_idx，disc_svc）;在user_catch_rest_hndl（）中调用。gattc_sdp_svc_ind意味着服务发现表示已找到服务，因此在找到新服务后，触发句柄_svc_ind（）。如果在HANDER_SVC_IND（）中检查代码，则会看到它发现BAS（ENABLE_BAS）和IAS服务（ENABLE_IAS）发现。服务发现后，您可以按中心设备上的按钮。这将写入警报服务，并开始在邻近记者上闪烁LED。如果正确发送，您还应该看到终端的写入。
So, when the button is pressed, then the user_ble_gatt_write() is called in order to write to the IAS.
In the case of the custom service (SVC1_IDX_LED_STATE_VAL), you should follow the same procedure. Discover the custom service in the handle_svc_ind() and then perform a GATT write to the correct attribute handle.
Thanks, PM_Dialog

Hi BenjaminDu,
Thanks for your question. You can use the BLE notifications. Please check theDA14585/DA14586/DA14531 Central Implementationthat demonstrates how to perform GATT reads/writes as a Central.
In the user_ble_gatt.c source file, you will find the user_ble_gatt_write(). That function performs a gatt write. You should send a GATTC_WRITE_CMD command to the stack.
Thanks, PM_Dialog
