BLE advertise data length

[Lmali.1]

Hi

I couldn't find a specific definition of the total length that I can advertise.

On one place I saw 37 bytes, on another place only 25 bytes.

Can someone tell me, how many bytes can I advertise?

Thanks,

Lior

Using the aci_gap_update_adv_data() call i got it working up to 31 bytes. (flag, single 128bit uuid, advertising name)

Ive found the following stackoverflow thread very helpfull in understanding the limits and requirements.
