Hey guys,
I have a peripheral running Nordic softdevice (BLE 4.0 protocol). Central
is running nimBLE stack 1.0 (0db6321a75deda126943aa187842da6b977cd1c1).
The peripheral advertises manufacturing data. I am trying to get to it from
the central. I never get the mfg data though. The advertisement packet
looks like this at the central:
> (gdb) p/x *fields
> $1 = {flags = 0x6, uuids16 = 0x0, num_uuids16 = 0x0, uuids16_is_complete =
> 0x0, uuids32 = 0x0, num_uuids32 = 0x0, uuids32_is_complete = 0x0,
> uuids128 = 0x20006750, num_uuids128 = 0x1, uuids128_is_complete = 0x1,
> name = 0x0, name_len = 0x0, name_is_complete = 0x0, tx_pwr_lvl = 0x0,
> tx_pwr_lvl_is_present = 0x0, slave_itvl_range = 0x0, svc_data_uuid16 =
> 0x0, svc_data_uuid16_len = 0x0, public_tgt_addr = 0x0,
> num_public_tgt_addrs = 0x0, appearance = 0x0, appearance_is_present =
> 0x0, adv_itvl = 0x0, adv_itvl_is_present = 0x0, svc_data_uuid32 = 0x0,
> svc_data_uuid32_len = 0x0, svc_data_uuid128 = 0x0, svc_data_uuid128_len
> = 0x0, uri = 0x0, uri_len = 0x0, mfg_data = 0x0, mfg_data_len = 0x0}
Everything else adds up, except no mfg data. Worth noting that I can see
the mfg data if I use another BLE central to scan.
My discovery parameters are as follows:
disc_params.filter_duplicates = 1;
disc_params.passive = 0; // active scan
/* Use defaults for the rest of the parameters. */
disc_params.itvl = 0;
disc_params.window = 0;
disc_params.filter_policy = 0;
disc_params.limited = 0;
Any ideas or hints as to how I can debug?
