Maximum extended advertising data length in SDK17

[Deya]

i noticed that in the "ble_gap.h",  #define BLE_GAP_ADV_SET_DATA_SIZE_EXTENDED_MAX_SUPPORTED (255). But now the situation is, i want to broadcast data more than 255 bytes, like 1650 bytes, which is allowed in the Bluetooth Core Specification. Is there any ways to get that?

Hello,

BLE_GAP_ADV_SET_DATA_SIZE_EXTENDED_MAX_SUPPORTED (255). But now the situation is, i want to broadcast data more than 255 bytes, like 1650 bytes, which is allowed in the Bluetooth Core Specification. Is there any ways to get that?

The nRF5 SDK does unfortunately not support chained or periodic advertising, no.
If you would like to use these features you will have to make use of the nRF Connect SDK.
The SoftDevice controller does not yet support periodic advertisements either, but the nRF Connect SDK supports the Zephyr controller which does - which you may then use to do periodic advertisements.

Please see this statement regarding the future of the nRF5 SDK and the nRF Connect SDK.

Best regards,
