你好，我提问一个问题：
如果使用外部flash芯片,比如DA14585开发板上w25x20cl 芯片来实现外部flash启动，启动完毕是不是外部flash将不再使用；
直接让外部flash进入低功耗就好了；
在training_04_sleep_mode_configurations_and_power_measurement_0文件中有关
Measuring the Extended sleep mode without OTP copy (DA14585/6)这一部分中；
蓝牙广播间隔修改为6s后测得功耗为3.4ua；
/// Minimum interval for advertising
.intv_min = MS_TO_BLESLOTS(6000), // 6000ms
/// Maximum interval for advertising
.intv_max = MS_TO_BLESLOTS(6000), // 6000ms
Hello,
I am working on a low power application, where I want my sensor to be turned ON only for a certain period of time, so that it should not consume power when not in use (rather when the ble in in sleep mode). So, I thought if I could provide supply to the sensor through GPIO Pin itself. The sensor would consume around 500uA of current. I thought of using a transistor first, then ended up concluding that it would need more power.
Please let me know, is it possible to draw that much current through the GPIO pins?
or
Hello,
I have a question regarding using multiple I2C busses on the DA14585. I am working with MCP9600 thermocouple amplifiers which have 8 possible addresses each. I need to connect 64 of these sensors to a DA14585 and read them at ~1Hz.
The extend sleep current now I measured on my custom board is about 10uA, that is bigger than 4uA, my system need i2c and spi, I initialized the i2c and spi at every wakeup in periph_init, does this 6uA(10-4 = 6) caused by the i2c_init or spi_init?
Chip: DA14585, SDK:6.0.14.1114, no 32.768K used.
Hi,
Any chance of getting the source code for Suota.
I am considering to port it to PC, perhaps python.

Hello Dialog support,
I am working on a script using SmartSnippets to program via UART. In our programming jig the connections are sometimes bad, and the programming fails with messages like
Hi,
I have a DA14585 IoT Multi-Sensor Development Kit, I am able to run example code using Booter of smartsnippets tool and also in debug mode, but when i flash the code (ex: multi_smart_tag_585.bin) in flash memory, it is not working, but the code is flashed successfully. I didn't give any offset.

Hi,
Which is the default firmware that is given in DA14585, and where can i download it from ?.

Hello Dialog Support,
we want to modify our firmware (HEX file) after compilation, so that different devices will have different names (without having to recompile). It seems that the devices do not boot with the modified HEX, I guess there is a checksum involved somewhere.
Hi,
I'm evaluating DA14585 now.
And I'm looking for a Sample Program which moves to Sleep Mode automatically during no communication.
Is there any recommended sample for this?
It will be better if it can be tested easily in order to estimate the actual current consumption.
Thank you.
