DA14580 UART, strange behavior

Dear all,

maybe it's all normal, since i am quite new to BT and dialog chips.
A board i am working on has DA14580, it has been wired to be controlled
trough UART.
But, immediately after the board boot, i see with oscilloscope a strange BT
chip traffic on both UART TX and RX, like some continuous burst of data.

Is it possible the module is bootstrapping in a non-UART mode ?

Eveyr help is appreciated.

Hello Angelo, sorry for the

Hello Angelo, sorry for the delay : this could be the boot sequence - the device has an automatic boot squence in development mode where it is looking on UART and other interfaces.

Hi Angelo,

Hi Angelo,

Because there is no application programmed in OTP, DA14580 would boot from serial interfaces.

Please refer to the doc below for details 

"AN-B-001 DA14580 Booting from Serial Interfaces"
