One BLE is set as MASTER BLE , if i want to change or add the some configuration settings in MASTER BLE , how to do it , after set as MASTER , Can i Access the MASTER BLE through android app , else do i have to change the MASTER into SLAVE...and how to do it ??
Hi, I'm developing a device in Korea.
I'm using the DA14580 Development Kit - Pro.
I developed the device based on "SDK5, ble_app_peripheral example"
My device needs the function that the device sends(or notifies) the value to the smart phone "when I push the button".
The value is updated by "app_easy_timer(APP_PERIPHERAL_CTRL_TIMER_DELAY, app_adcval1_timer_cb_handler)"
Isn't it? (If you see the example, 'user_custs1_impl.c' , you can get it)
And I add the button source code to use it at the
In a production line setup we are trying to use SmartSnippets command line interface to burn the OTP header and OTP custom code. Both work from Windows GUI, but fail from command line.

Dear Dialog,
I'd like to know following points about DA14580's central operation mode.
Q1: We observed that rssi seems to have strong dependancy to the scanning channel. When we set 5seconds
for scan interval, we saw 5 seconds'periodic change of rssi by almost 10 - 15dBm change even the distance
of central and peripheral is fixed and experiment is conducted in the shield room.
Can you explain this phenomenon?
We have checked there is only a very slight varience like 1dBm for peripheral's transmit power.
Hi
1.How to implement wake up from sleep mode by using wakeup timer ? What is the maximum time we can set for timer? Please mention example code.
2. After wake up we will do advertising of slave and we want to set advertizing interval of slave each time incremeting i.e. everytime we will increase the sleep time. So where we will find advertizing interval in DSPS code?
1.Can you please provide Battery level monitoring reference design for 14583 based design
2. Is it required to add buck booster in battery operated design?
3. Can we make provision of PCB as well as coaxial type antenna in same design and how to do this?
4. In line of site, how much is the distance covered by using PCB type antenna as well as using coaxial type antenna?
Hi,
when trying to use the commandline interface of smartsnippets - 3.9 - i always get this errror:
Invalid argument -bootable for command write with type spi.
Usage:
SmartSnippets.exe -type spi -chip chip_version [-clk clk] [-cs cs] [-miso miso] [-mosi mosi] [-jtag jtag_serialNumber | -com_port portNumber] [-baudrate rate] [-gpio pinId] [-uart TxId] [-firmware firmware_file] -cmd write -file filename [-offset ofst] [-max size] [-verify] [-y] [-nomessages messageFilter]

If we want to add additional I2C and SPI drivers to the existing DSPS device project, Where and How to add them in the Project Window/File system ??
In DSPS device project, How to Change the time of slave Advertising Interval ? How can we increment it periodically ?
Please mention the filename which contains slave advertising parameters.
