Hello,
Can you please provide details of configuring DSPS device project for EXTERNAL_WAKEUP via UART CTS.
From AN-B-026 : External Processor Wake-up Mechanisms document the feature is described for full embed only. It is not clear how to apply it to DSPS.
The idea is to wake up DSPS (device side) by an external processor, transmit a burst of data and than return it to extended sleep.
Your help will be greatly appreciated.

I have a characteristic value is more than 100 bytes, and App layer need to use it periodically. Can I use attmdb_att_get_value to read it when needed ?
感谢任何帮助!
Hello,
I have connected a SPI flash memory following the indications on the AN-B-023 document, the memory is a Microchip SST25PF020B. My problem is that when I try to burn the memory using smartsnippets (Yes, i do an erase before that) it says that it was completed sucessfully, but reading the memory after that returns the same contents as they were before (All 0xFF). I have triple checked the connections, schematics and PCB boards and everything is looking good. Any guidance on where to look to solve this issue will be highly appreciated.
In the battery.c(smarttag):
//////////////////////////////////////////////
adc_init（gp_adc_se，gp_adc_sign）;
adc_enable_channel(ADC_CHANNEL_VBAT3V);
adc_sample = adc_get_sample（）;
adc_init(GP_ADC_SE, 0);
adc_enable_channel(ADC_CHANNEL_VBAT3V);
adc_sample += adc_get_sample();

Dear Team,
could you please advise on how to create a firmware to scan a beacon? So to say other counterpart of the "Beacon ref design".
Thank you

According to UM-B-012 DA14580 Creation of a secondary boot loader, my application can be booted successfullly when second bootloader burned into OTP. but When second bootloader was burned into external spi flash(address offset 0x0), It can not boot my application. I don't know why?
Recently,I test the power consumption of "sample128_After section 6.2" when in advertising state,
I set :
APP_ADV_INT_MIN=APP_ADV_INT_MAX=3600
define CFG_DEEP_SLEEP
define development_debug 1
and add the following code in function app_adv_func()：
/////////////////////////////////////////////
if (APP_ADV_INT_MAX >3200 )// > 2000 ms
app_set_deep_sleep();
else
app_set_extended_sleep();

Hi,
We do some modifications based on "DA14580_DialogBeacon_3.40.6" reference designs, For checking the power consumption, first, we stop the advertising, it is work, but, I can read a periodic current waveform at about 10 seconds that means device ever active by itself. All of my created timers, we have not started any timer count for 10 seconds except a 60 seconds one. However, we need to avoid this status happened, how can I stop it, or make it longer?
First what I want to have: My application must advertise for a few seconds, triggered by an external interrupt input. Then the device should go the extended deep sleep, till the next trigger. The application should run in a SPI flash memory, during the development phase. Nice to have will be the SUOTA and the battery service. But it is not so important in the moment - I think, this are not too big requests.
Hello,
I consider the DA14508 for an application where want to drive a vibration motor. E.g. (https://www.parallax.com/sites/default/files/downloads/28822-Vibration-M...)
Therefore the question: how much current can the DC-DC converter (VBAT3V) supply?
