Re: Digest for btstack-dev@googlegroups.com - 1 update in 1 topic

Hi Matthias,

I am looking forward to BR/EDR (Classic) and the intention is to let the application know that page scan has started after issuing gap_discoverable_control(1) command.

In the same way I want to let the application know about the disconnection after the gap_discoverable_control(0) command is issued.

From the BTStack Manual, Under profiles I see below code snippet

int main(void){ ... // make discoverable gap_discoverable_control(1); btstack_run_loop_execute(); return 0; } void packet_handler (uint8_t packet_type, uint8_t *packet, uint16_t size){ ... switch(state){ case W4_CHANNEL_COMPLETE: // if connection is successful, make device undiscoverable gap_discoverable_control(0); ... } }

However I am not able to trace W4_CHANNEL_COMPLETE in the source code.

Thanks

Justin

Callback to verify if the advertisement is turned on/off

Matthias Ringwald <matthias...@gmail.com>: Aug 05 10:01PM +0200 Hi Justin   gap_connectable_control() controls the BR/EDR (Classic) Page Scan Mode. For LE, you would call gap_advertisements_enable(on/off) after setting adv params with gap_advertisements_set_params and data with gap_advertisements_set_data   Why would you need to verify that? If you insist, you can check if you get a HCI Command Complete for LE Advertisements Enable with status code = 0. (but you still need to trust the stack that it sends on / off as you expect)   Cheers Matthias

Hi John

Could you tell why you want/need to know when the page/inquiry scan mode has changed?

When you call gap_discoverable_control, the stack will send the corresponding HCI Command immediately and the scan mode will change within a few milliseconds 

Best
