DA14531

Hi, folks,

I can set the prox_reporter project to do advertising timeout and go to extended sleep.  This is fine--the advertising does a couple of bursts and then goes to extended sleep.  I get somewhere around 1.6uA of current or so.

However, if I set "CFG_EXT_SLEEP_WAKEUP_TIMER1" and change *nothing else*, I get mA spikes at the advertising interval and it never stops.  That's no good.  It seems like timer1 is resetting the fact that the advertising is supposed to have timed out.

How do I avoid that?

Thanks.

Hi, folks,

I have a project that needs to wake up roughly every 15ms, do some basic GPIO stuff, and then go back to sleep.  No BLE needed.  Presumably I need to be in extended sleep mode so that I can use Timer1 to wake me up (I sure don't want to be reloading from OTP/Flash every 15ms) with RAM retention.

We already have a custom board built so we can avoid the issues with trying to get power numbers and having the dev kit driver board getting in the way.

Hi, folks,

I have a custom board that we've designed and been checking out.  I can boot the DA14531 to RAM using either Keil SWD via my Segger J-Link or SmartSnippets Toolbox 1-Wire UART.  It works fine.

The problem is that I can't get the SmartSnippets Toolbox v5.0.14.3080 to program the SPI flash.  It fails with "[ERROR    General            @21-01-24 22:39:22] No known chip found while opening JLink connection. Terminating proccess...".  This makes no sense as the chip programs via Keil SWD just fine.
