Why this happen and is there any solution to solve this problem?

and one more thing, what does -75 mean return from CloseRemoteServer() function?

Please refer to the BTErrors.h for details on the error codes. The -75 refers to the BTPS_ERRO_RFCOMM_INVALID_DLCI. The SPP_Close_Port() API might return this error when trying to close the port before the SPP profile level connection is completely established.

I have two CC2564B Board and connect both board with SPP automatically.

So use inquiry command to find target board, but it sometimes cannot find target board.

Do you see the same problem with the default(unmodified) SPPDemo/SPPLEDemo?

Best regards,

Vihang,

I'm testing Inquiry() function with MSP430 SPPLEDemo on each board and there is some problem.

at first it seems fine but It does not find each other after about 100 seconds.

I've been waiting over 5 minutes and it does find each other sometimes, not always.

but It's just a moment, they does not find each other soon.

is there any advertise timeout or something for power saving?

if exists, any parameters that i can modify?

why cannot they find each other?

Dong, please provide the BT firmware logs from the TX_DBG pin of the CC256x so that we can look further into this.
