Get Status 95 on ACI Command 1B

[i_am_trying]

I want to change data bytes in the advertisement packet. In ACI_DEVICE_STANDBY I put: lib_aci_open_adv_pipe(1);

In ACI_EVT_CMD_RSP: I get feedback that command 1B (I assume this is the open adv pipe command but I am not sure where the mapping for aci_evt->params.cmd_rsp.cmd_opcode is) STATUS is 95.

What am I doing wrong?

Thank you.
