# Set STEVAL-IDB006V1 in advertising mode

I have a BlueNRG USB Dongle (IDB006V1) Eval board that I'd like to set in advertising mode but I just can't get it there as it throws a HCI_HARDWARE_ERROR_EVENT.

I've install the BlueNRG GUI and the dongle is recognized so I opened the corresponding COM port (ST DK). I then updated the firmware BlueNRG-MS_stack/bluenrg_7_3_Mode_2-32MHz-XO32K_4M.img what seemed to work.

In the ACI Utilities I first do Init Device... with the default settings.

• Role = ALL
• Stack Mode = 2 (my assumption according to the select file above)
• Tx Power Level = -2dBm

This finishes with a HCI_COMMAND_COMPLETE_EVENT so I assume it was successful. I then try to set it to Advertising... with the following settings

• Mode = GNERAL DISCOVERABLE MODE
It then does a HCI_LE_SET_SCAN_RESPONSE_DATA and ACI_GAP_SET_DISCOVERABLE which both return HCI_COMMAND_COMPLETE_EVENT but then I get the HCI_HARDWARE_ERROR_EVENT, a few seconds later a ACI_BLUE_INITIALIZED_EVENT.
The error details state that is was a Timer overrun error most likely related to the SPI bus, but that should be part of the FW image? So what am I missing?
Sometimes you just have to get a different point of view. Turned out I've to load the 16MHz Firmware instead of the 32MHz. Usually the ST Manuals are quite good, but on this I'm missing some guidelines that would ease up the whole "getting started" process.
