Development Mode without XTAL16M/XTAL32K
Hi,
I am using Murata ZY type which uses DA14580.

is there any disanvantage?

keyboard disconnecting
When I pressed "Y" and "H" all the time, I hit the key "K", I found the key "K" was reported by sending notification through GATT suscessfully as it causes a GATT_NOTIFY_CMP_EVT message . Howerve the peer device seem to don't receive the key. I hit the key "K" more times, the connection lose.

DA1458x QFN 40 5x5mm orcad symbol
Hi Dialog,
To speed up the design effort, may i know if there is any orcad symbol for both schematic and layout qfn40 5x5mm available to download? this will help to prevent any symbol creation issue and also help developer to have hassle free to create symbol.
Thanks.
Warmest regards,

Please Reconsider removing the AD flags from the advertising packet
previously discussed in the posthttp://support.dialog-semiconductor.com/removing-ad-flags-advertising-pa...that it's illegal to send no flag AD.
But the fact is that BLUETOOTH SPECIFICATION permit no flag AD,“ The Flags AD type shall be included in the advertising data if any of the bits are non-zero. The Flags AD type may be omitted from the advertising data if all of the bits are zero.”
so please reconsider the unneccesary limit.Currently is it possible to send no flag AD?
Can OTP programmed by JTAG
Hi~
Can I use JTAG to program the OTP ?
I have read the document . It mentiones the JTAG can be an optinonal signals between interface board and da14580. So, I wonder whether the OTP progamming can be done by JTAG.
Thanks!
