BlueNRG-MS GATT不能执行

大家好，


我有一个基于BlueNRG-MS的GATT服务器，它有几个特性，我能够从Android读取和写入这些特性。现在我需要使用BlueNRG-MS实现GATT客户端来访问另一台设备上的GATT服务器。我可以使用aci_gap_create_connection（）连接到服务器，但是在建立连接后我既不能执行aci_gatt_disc_charac_by_uuid（）也不能执行aci_gatt_disc_all_charac_descriptors（）和aci_gatt_write_charac_value（）。任何这些功能的返回状态都是正常的，但是在客户端和服务器端都没有收到相关的事件。我在一段时间后得到的唯一事件是EVT_DISCONN_COMPLETE，其中reason = 8（超时）。

实际上我不太了解aci_gap_create_connection（）函数的参数min_conn_length，max_conn_length，conn_min_interval，conn_max_interval和conn_latency。我试着调整它，但没有运气。

任何人都可以帮我解决这个问题吗？

Hi all,


I have a BlueNRG-MS-based GATT server with several characteristics, and I'm able to read and write these characteristics from Android. Now I need to implement a GATT client using BlueNRG-MS to access the GATT server on another device. I'm able to connect to the server using aci_gap_create_connection(), but I can't do neither aci_gatt_disc_charac_by_uuid() nor aci_gatt_disc_all_charac_descriptors() nor aci_gatt_write_charac_value() after the connection is established. The return status of any of these functions is OK, but no relevant events are received neither on the client nor on the server side. The only event I get after some time is the EVT_DISCONN_COMPLETE with reason = 8 (timeout).

Actually I don't quite understand the parameters min_conn_length, max_conn_length, conn_min_interval, conn_max_interval and conn_latency of the aci_gap_create_connection() function. I tried to adjust that, but with no luck.

Can anybody help me with this problem?
