Extended Advertising with long advertising interval and extended payload size

[Christian]

Hi,

 

I want to implement Extended Advertising for broadcasting data with LE Coded PHY on the nRF52840 Boards with Softdevice S140 v6.0.0.

 

For Soft Device Version S132 there is a beacon example (ble_app_beacon) which does fit my purpose, however I want to use Extended Advertising with LE Coded PHY to achieve higher range. This example does not seem to be present for S140. Is there any similar example I can use as a starting point?

Aditionally in the Release Notes it says:

- advertising intervals longer than 10.24s are missing and

- the LL payload for LE Coded PHY is limited to 27 Bytes.

 

Is there any possibility or workaround to have longer advertising intervals and extended advertising payload as decribed in the Core Specification for BT5? Especially a longer advertising interval would be crucial for my evaluation as it depends on low energy consumption.

Best Regards

Sorry for the late response Christian,

 

We do not have any example for AE in the SDK now, we are working on it.

Until then you can use a modified att_mtu_example that I modified to test AE for long range. Use this as an example as I did this as my hobby side project.

ble_app_att_mtu_throughput_25_04_2018.zip

 

No, unfortunately, there are no workaround for that in the released version. We are working to extend that feature to support longer adv and longer LL payload

Hi Aryan,

Thank you for your answer and for your sample project, this helps a lot. 

Are there any information on when these features will be released? Are they planned for the next major release of the Soft Device or might they become available in a minor point release in the near future?

I can totally understand if there is no information on this, but if it is I would be glad to know.

Regards

Hi Christian,

We might add AE example in the next SDK, but please do not consider this as a promise. This is a very important feature and our SDK will not miss an example on it for too long.
