How to enable Bluetooth 5 long range advertisements

[Peter Lerup]

Hi,

I'm experimenting with the nrf52840 preview board.

I have tried the example "ble_app_att_mtu_throughput" using the coded option to check the extended range and it works fairly well. I heard that there is a bug in the sd which cripples the actual range though...

My question is regarding extended range advertising. It looks like the BLE_GAP_PHY_CODED option is something that is set up via negotiation during the actual connection.

What is the proper way to set up advertising so that BLE 5 devices can get the extended range during advertisement phase.

Thanks /Peter Lerup

In order to create connections on coded phy, you need to make use of the advertising extensions. These are supported in the latest alpha (s140 5.0.0-3). I haven't had a chance to play around with it, but there is an example inside the release that you can use.

It's called ble_app_att_mtu_throughput_example_connecting_on_long_range.zip and resides in the public folder.

Sorry for being a noob, but where is that public folder?

[Petter Myhre]

It is in the SoftDevice zip. Downloadable here.

Great, thanks!

Ulrich, in the document "s140_nrf52840_5.0.0-3.alpha_migration-document.pdf", there's a comment saying:

"A new configuration option, BLE_GAP_CFG_ADV, has been added to the sd_ble_cfg_set(). This option can be used to configure advertising sets. Currently this option is not used as this alpha release only supports one advertising set with 31 bytes of advertising or scan response data."

Does this mean that extended advertising is not yet supported in this release?

The Advertising Sets feature is only a part of the Advertising Extensions. That part is not completed yet, but we wanted early feedback on our API.
