Hi All

1. I Just call once GATT_DiscPrimaryServiceByUUID In SimpleCentral.C , but ATT_FIND_BY_TYPE_VALUE_REQ was sent twice. when i comment function GATT_DiscPrimaryServiceByUUID,

no one ATT_FIND_BY_TYPE_VALUE_REQ was sent

2. start handler was 0x0001 defalut ,but start handler was 0x0024 in the Second ATT_FIND_BY_TYPE_VALUE_REQ.

The documentation of GATT_DiscPrimaryServiceByUUID() in gatt.h states:
"The primary specific service may exist multiple times on a server."

It appears that the BLE stack is trying to find all instances of the service you requested.

I am also facing the same issue, even the GATT server has only one primary service registered. But on sniffer I am seeing two call as mentioned in first post.

Can any TI member verify this?
