no mfg data during scan response when bt_data_parse

[Simon]

Hello,
the device name is being parsed ok, but the mfg data in scan response seems to be there but not sure how to print it out.
Using ncs bt sample direction_finding_connectionless_rx modified for nRF52840DK since it was using bt_le_scan_recv_info and bt_data_parse.
The nrf terminal is showing the name for Thingy-1, but not the output for mfg of data_len 6 during case BT_DATA_MANUFACTURER_DATA.

How best to get mfg data in scan response?

ok, ....thank-you,
