Hi Dialog,
I am using the sample code: ble_app_peripheral from SDK 6.4.2.
Ionlymodified the variableapp_default_sleep_modefromARCH_SLEEP_OFFtoARCH_EXT_SLEEP_ON
I am very confused...If I burn the code into RAM (SmartSnippets -> Booter -> Download), it works.
However, If I burn it into external flash, it will advertise but just a while. The mobile app can find the device but the device disappears almost immediately.
It seems like DA14585 doesn't wake up sfter sleeping...
I find that if I connect to DA14585 immediately when the first advertisement, the connection will be normal, so I change the advertising interval from 600 ms to 30 ms. There is no any problem...
How should I do? Do you have any ideas? :(
Thanks a lot.

Hi stanley_yeh,
I ve tested the ble_app_peripheral project as is, i dont see any issues to the project if burned on flash, and i dont see any connection between the advertising intervals which could be related to the burning of the flash. If you try to download the fw via keil, does the device acts the same ?
Thanks MT_dialog
Hi MT_Dialog,
I touch a specific area of our board with my finger, DA14585 will be normal every time. I don't know why. It's weird.
I think it is not software issue and I hope so.
Some of our RDs feel that DA14585 is sensitive, I am sorry but we really don't know how to describe that.
When we feel it is abnormal, sometimes we just touch the pins which is connected to DA14585 and it will be normal.
Ummm...That's OK.
I am grateful for your help, thanks a lot.
