Updating advertising data between iBeacons and AltBeacons

Thanks for the update. So I guess the Altbeacon payload is 31 bytes when flags and length fields are included.

The length was modified to 30 for iBeacons. Hence that AltBeacons were being truncated when I switched back to transmitting them.

Yes, that worked perfectly. Thank you.

Hi,

Yes, the default length is 31. Please try to pass 31 as the input length when encoding the AltBeacon data, then check what the length of the encoded data becomes.

Best regards,

Hi,

What is the default length? Is it 31? I refresh it to the length of the block that I am encoding (24 for AltBeacon and 23 for iBeacon).

Thank you,

Zia

Hello,

Please make sure m_adv_data.adv_data.len is always re-initialized to the default length prior to calling ble_advdata_encode().The p_len input for ble_advdata_encode() is also used to output the size of the encoded data, which may explain why data gets truncated when trying to encode the larger AltBeacon payload.

Best regards,
