Thanks!

Hi Oliver,

Hi Oliver,

If you want to use HCI mode then you will need a DA14581 device. Details of how to use that device in HCI mode can be found in the following application note:

Hi IM_Dialog,

Hi IM_Dialog,

thank you for the information.

Is the USB Dongle included in the "DA14581 Development Kit - Pro" equipped with DA14581?

Best regards,
Oliver

Hi ibbkoein,

Hi ibbkoein,

Pro-mother委员会提供的电子狗是dev kit, but the dongle isn't equipped with a DA14581 but with a DA14580 that doens't support HCI commands.

Thanks MT_dialog

Hi MT_dialog,

Hi MT_dialog,

so I have to design my own dongle... Is there a reference design (schematics) available?

Can I program the file hci_581_active_uart.hex from DA14581_HCI_581_3.110.2.12\binaries directly into the OTP without any changes? Because it's OTP I only have one chance and I don't like soldering out the chip several times ;-)

Why can't I use e.g. DA14583 for HCI?

Thanks,
Oliver

Hi ibbkoeln,

Hi ibbkoeln,

All the reference designs are in the reference design section of the support site, you can also have a look at the Documentation tab of the 580, in the Development Kit Documentation section there is a document UM-B-001 that includes the schematic for the dongle (with the 580).

The 581 has an improved ROM code and that version of the ROM code is the one that support the HCI commands defined by the spec, the 580 and the 583 dont support HCI commands.

Yes you can burn the 581's OTP, regarding burning directly the files from the binaries folder in the OTP that depends on the configuration you would like to have on the device, i am not aware if those .hex files were compiled with the DEVELOPMENT_DEBUG set or the BOOT_FROM_OTP for example (i assume that they are not), so the best it would be to compile and burn your own image and have those .hex files for testing.

Thanks MT_dialog
