Hi guys,
I have two characteristics, one for get values from mobile application
and the second one is to reply as notification to user, to the mobile application.
I registered to notification characteristic, to reply the user for any changes.
I have two issues with Characteristic Notification.
- From some reason, when the mobile application send to the write characteristic an array of more than about 25 bytes, and than I send a notification, the result of the function is ok, but the application doesn't receive the notification. If I send less than about 25 bytes, the application receive the notification message.
- When the application send a short array f bytes (let say around 10), the application receive the notification, BUT if the application send again a short array of bytes, the application doesnt get the notification.
This is code of the notification character:
aci_gatt_add_char(AdminService.AdminServiceHenale,
UUID_TYPE_128, &uuid16,
100,
CHAR_PROP_NOTIFY,
ATTR_PERMISSION_NONE,
GATT_NOTIFY_READ_REQ_AND_WAIT_FOR_APPL_RESP, /* gattEvtMask */
7, /* encryKeySize */
1, /* isVariable: 1 */
&(AdminService.ConfigStatusHandle));
and this is the sending of the notification:
result = aci_gatt_update_char_value(AdminService.AdminServiceHenale,
AttrHdle,
0, /* charValOffset */
len, /* charValueLen */
(uint8_t *) pPayload);
Thank you for your help!
