CC256XM4BTBLESW: Lost Pairing on Reset Device

Part Number: CC256XM4BTBLESW

I work with the SPPDemo.

I send to SPPDemo:



pair 1 1

open 1 1

Then the port open needs 100 ms to connect.

When I reset the device, and send


open 1 1

the Open needs 3000 ms

The System have Lost the pairing.

What can I do to hold the pairing after reset?

I write back the KeyLink from

I write back the LinkKeyInfo with LinkKey Values what I get from atLinkKeyCreation after pairing bevore reset.

But  SPP_Open_Remote_Port does not use LinkKeyInfo.

And I get no Authentication callback from remote device after SPP_Open_Remote_Port.

This is the reason I can not send GAP_Authentication_Response with the LinkKeyInfo to the Device.

What we need is, the same speed for SPP_Open_Remote_Port then bevore Reset.

I dont want send an pairing after reset because it is too slow.
