Hi,

there are few things you didn't take into account:

- each record starts with two-byte header (record length + record type)

- company ID is a part of manufacturer data record

- include_appearance means that your advertising should include 16-bit appearance value

- there is additional "flags" record (8-bit) that is mandatory for connectable advertisements

Now let's count: 1+1+4 (name), 1+1+2+14 (company id and manuf.data), 1+1+2 (appearance), 1+1+1 (flags) - total 31 bytes.

Update:
Commenting the following lines in the advertising_init function of the main.c file:

//init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
//init.advdata.uuids_complete.p_uuids  = m_adv_uuids;

now i can send 20 bytes divided in:

Are there some other data sent by this template?

Thanks.
