CC2564MODA: how to initiate connection after disconnection with smart phone

Hello,

We are using CC2564 duel mode chip and bluetopia stack for bluetooth communication. We are initiating initial connection (pairing) from smart phone. When smart phone gets disconnected, we want our device should initiate re-connection by sharing link key. For that purpose we have used the API GAP_Authenticate_Remote_Device().

But this API starts authentication successfully when device is already connected. This API returns error -1 if we try to connect disconnected but paired device.

Thanks.

What profile are you using? Connection APIs vary across profiles.

Hello,

Apologies for the delay. To send a connect command over HID you can use HID_Connect_Remote_Device. The HIDDemo application has an example of this and the HIDAPI.h describes the interface in detail. For HFP you use HFRE_Setup_Audio_Connection and similar to before, you can find an example on this in our HFP example and HFREAPI.h.
