Perform the following steps to verify advertising intervals.
Open a terminal on the DUT, and execute
$ btmon
Open another terminal on the DUT, and register an advertisement.
$ ./example-advertisement
Observe that the default intervals are 1280 msec in btmon log.
< HCI Command: LE Set Advertising Parameters (0x08|0x0006) plen 15
Min advertising interval: 1280.000 msec (0x0800)
Max advertising interval: 1280.000 msec (0x0800)
Press ctrl-c to terminate the advertisement.
Set new intervals to 200 ms.
$ ./example-advertising-intervals 200 200
It would show the following line in btmon log.
= bluetoothd: Set Advertising Intervals: 0x0140, 0x0140
Register an advertisement again.
$ ./example-advertisement
Observe that the new intervals bcome 200 msec in btmon log.
< HCI Command: LE Set Advertising Parameters (0x08|0x0006) plen 15
Min advertising interval: 200.000 msec (0x0140)
Max advertising interval: 200.000 msec (0x0140)
Press ctrl-c to terminate the advertisement.
