Dear Sir,
This is Vishnu, I bought DA14583 IoT Sensor Development Kit.
I am having some doubts, please clarify
1. Is the sensor dongle module is programmed or we should program that with smart snippets?
2. In DA14583 Wearable Reference Design the port P0 is used as serial communication(SPI) or I2C communication?
3. What is the difference between the VBAT and VBAT_mag?
4. In DA14583 datasheet, it mentioned as Port P2 has four special pins which are used SPI Bus Interface. What is the difference from Port P0 to Port P2 in context of SPI communication?
5. In DA14583 Wearable Reference Design, what is meant by NP and 0 at resistance displayed locations? ex: R35 NP, R34 0
6. In DA14583 Wearable Reference Design, there is one decoupling capacitor connected C31 still Why one more capacitor C4 =2.2 uF is connected from the battery holder to VBAT and
VBAT_RF pins.
7. When Sensor Dongle is connected with the external smart-phone/tablet, how to read the sensors raw data in values? like acceleration 2g, angular velocity 100 deg/sec.
8. After connecting Sensor Dongle to the smartphone, the android app can set to the fusion mode. When it is fusion mode the external movement in the sensor dongle is showing on the
screen, but the stabilization time from movement to rest position is taking time why it is happening like that?
9. The sensor Dongle is powering up using BR1225 coin cell battery, what is the life time of the battery if it is continuously working?
10. As it mentioned in the power specifications what is the difference between the Connected: < 1.3 mA; Advertising: < 110 uA; modes. Is connecting smartphone to sensor dongle module
in advertising mode?

DA1453 IoT Sensor Development Kit
Device:
Hi vishnuatdialog,
1) The device should have the fw allready in the flash when you open the box, but you can use the Smart Snippets and re-program the flash with any fw that you would like.
2) The P00 port/pin is used as a data out pin for the SPI of the sensors available, you will be able to check this on the schematic of the board, on the document UM-B-064 on table 4: sensor and GPIO pin assignment and also in the set_pad_functions() function that sets up the functionallity of the available GPIOs.
3) What do you mean if there is a difference the VBAT is the power supply of the 583 and the VBAT_mag is the power supply of the magnetometer.
4) None, the 583 has an internal flash in package, so there are internal connections between those pins and the internal flash, other pins can also be assigned with SPI functionallity.
5) NP, stands for non-populated, and the 0 ohm resistors are used for debugging, configuration or manufacturing purposes.
6) The extra cap is there for additional filtering on the VBAT, this is also mentioned on the design's schematic.
7) The IoT fw operates with the IoT sensor application, but you can connect to the device via a generic app and trigger sending data by writing to the Control Point characteristic (you will be able to find which of the available characteristics this is by using the UM-B-063 DA14583_IoT Sensor Development Kit on Table 6) the value 0x01, that will trigger the device to start sending raw data in the corresponding characteristics (remember in order to see that data on the phone side you will have to enable the notifications as well). Please check the previously mentioned document for checking the available options for the configuration of the sensor.
8)试图校正磁强计,procedure will improve how the device responds (calibration procedure is explained on the document mentioned).
9) The power consumption of the device is mentioned in every single state of the device, and the lifetime of the battery depends on the state of the device, so how much the device consumes when the device continusly working if a bit vague (since continusly working means a lot of things, continusly advertising, is continusly connected with a central, is continusly connected and sends sensor data, etc). So depending on what the device does you can easily calculate the lifetime of the battery.
10)广告和连接是我所使用的术语n BLE technology in order to indicate what the state of the device, advertising means that the device is not connected with a central and it advertises itself in order to be found by a scanning central, so that the central can issue a connection request and so that the devices can be connected and exchange data. When the two devices are connected it doesn't mean that they exchange data. Please check some BLE sources in order to get some basic understanding of the BLE specification.
Thanks MT_dialog
Thank you MT_dialog.
