Bluetooth Low Energy Power Profile : Why the module advertises 3 times and why the RX radio is needed ?

Hello everyone,

I'm looking the power profile of the advertising event for the S140 stack but two points trouble me.

• Why the module advertises 3 times ? One of the new features of the Bluetooth 5 is that it doesn't need to send 3 advertising packets per event.

• Why the powered of the RX radio is needed since the packet is broadcasted over the air without acknowledgement packet ?

Thanks in advance,
Sylvain.

  • Hi,

    I am trying to browse through forums to get the appropriate answer for configuring scan channels configuration. Most of the posts are bit old. I am not able to create new post, hence the posted again!

    Is there a possibility to configure or select a scan channel on which the central should scan only on those specified channel(s)? The use case is something like - "the scan should be CONTINUOUS on a specific channel, no channel hop delay."

    Currently our production code is on SDK10 with nrf51x SoC. Would be great if someone help me to understand the supported SDKs and nRF SoCs, if there a provision/support available. 

    We are planning to move to nRF52, trying to explore possibilities to support existing products and new nRF52832 based product with this configurable option.

    Thanks,
    BLEBOT

  • Hi,

    It is better to create a new question instead of "hijacking" an older thread, as that makes browsing the forum more difficult. Why are you not able to create a new question? (But the short answer is that there are no SoftDevice for the nRF51 that allow you to specify a single channel for scanning, it will scan on all channels, one after the other).
