Hi,
I have found the problem but don't know why!
When I connect my custom board with da14682 to my phone, the micro program enters in unknown state. for example I turned on one LED in start of the program but after 2 or 3 seconds, this LED will be turned off.
My application is USB_CDC plus DSPS project.
Thank you in advance.

Hi techteh :
Here is the feedback from the team:
, Android HOST which already support CDC class is compatible (can recognize and enumerates) with some custom USB CDC device vendor (FTDI....) But In the DA14683 device we are using specific VID/PID :
static const USB_DEVICE_INFO _DeviceInfo =
{ *0x2DCF*, // VendorId *0x6002*, // ProductId "Dialog Semiconductor", // VendorName "DA1468x/DA1510x CDC", // ProductName "12345678" // SerialNumber. }
;
There will be a work on USB CDC Android driver (USB Serial for Android Library) to support our device
Thanks,

Hi,
Thank you for your reply.
My problem has been solved. It was an issue with USB charger without battery presence. I set "dg_configUSE_USB_CHARGER" define value to 0 and now everything is OK.
Best regards.
