Hi again!

Well, some of this depends on what device, which SDK, which softdevice etc. you are using.

1. You can decide for yourself when the device should go to sleep.

2. This depends on so many things. I don't have any information about what you are doing in your code, except scanning and transmitting. I also don't know what device you are working with. You might want consider making a new post focusing on this.

3. Yes, that is possible. Take a look at this function:
sd_ble_gap_scan_stop()

There is a lot of information in our infocenter. Power specifications can be found in the device PS. Also, you can find so many Q&A's here on devzone, so a quick search might solve your issue.

Best regards.

Hi!

Ok, so your device will transmit the advertising packet on three different channels each advertising interval (ch.37, ch.38 and ch.39)

For a full 31 byte payload the radio is advertising for about 3ms on 3 different channels, or about 1 ms per channel.

Cheers.

Hi!

The advertising interval for non-connectable mode can be somewhere between 100ms - 10.24s.

You can however keep advertising forever.

Please let me know if you have further questions.

Best regards,
Joakim.
