Chained Advertisement

[Mihir Tailor]

Hello,

I am using PCA10040 development board based on nRF52832, Softdevice 6.1.0 & SDK 15.1.0.

On the Nordic website, I have verified that Softdevice v6.1.0 supports Chained Advertisement feature of Bluetooth 5.

But I cant perform Chained Advertising application.

So, I want to ask that does SDK 15.1.0 not having the feature of Chained Advertisement?

Thanks

Hello,

I have same setup (PCA10040 deb board with nRF52832, Softdevice 6.1.0 & SDK 15.1.0). I wanted to use the extended advertisement feature to advertise more than 255 bytes of data.

Looking to the release note, Nordic claim they support chained advertisement but in ble_gap.h header file, I see  BLE_GAP_ADV_SET_DATA_SIZE_EXTENDED_MAX_SUPPORTED = 255.

The BLE specification mentions that up to 1650 bytes could be sent in an extended advertisement. Maybe Nordic supports a limited number of chained packets but then the define in ble_gap.h does not match.

@Mihir: Did you manage to do some extended advertisement with data length > 255?

@Nordic support: Can you please help?

Thanks
