1-wire UART RX
Hi,
is there any example or guidelines on how to setup the 1-wire UART to actually send data from the PC to the DA14531 module? How should it be defined in the code?
Thanks
SCANF implementation
Hi,
is there any example on how to implement a function (and a handler) to manage messages received from the serial interface (e.g. via teraterm).
If not, is there at least an app callback in the "user_app_callbacks" list which I can leverage to write my own handler upon receiving a message from the serial port?
Thanks
Maximum data length transfer
Dear all,
For a project, I am using a DA14531 chip to transmit data from a sensor to a smartphone.
The sensor provides 16 bits every 2 ms (500 Hz) via SPI.
To transmit the data via BLE, I am using this piece of code:
DA14531-DA14585-586_Reading_I2C_Accelerometer_BLE code example not working
Dual role
Hi,
As i understand it it's possible to switch role between central and peripheral to scan or advertise, but you can't do both at the same time.
Then I wonder if it's possible in the peripheral role to accept a connection and then switch to central mode and start scanning while keeping the connection from the periperal role alive?
And also the other way around, while in central mode connect to a peripheral device and then switch to periperal role and start advertising while keeping the connection from the central role alive?

How to put variable length data received by serial port in an array?
During serial debugging, I encountered the following problems:
1. How to put the variable length data received by serial port in an array? What should I do to achieve it? This is critical to me.
2. When I am debugging, I continue to execute from the receiving interrupt processing function (uart_rx_isr) to the receiving callback function (uart_read_cb). After the receiving callback function is executed, press F11 to continue execution, and then jump to this function uart_rls_isr, I think Know under what circumstances will trigger this function (uart_rls_isr)?
Broadcaster/Observer role - acknowledge
Hello,
I have a small question about Broadcaster/Observer pair. I know that Broadcaster/Observer implement unidirectional communication.
我的问题是"It is possible to receiveacknowledge information from observer to broadcaster?"
My scenario:
I have two devices (sensor as broadcaster and receiver as observer), and I want to transmit some data (e.q temperature data) from sensor to receiver . And I want to know that the observer (receiver ) has received the information from the sensor (broadcaster), something like acknowledge.
Crystal trim and lld_sleep_compensate_func warning
Dear Dialog,
After tuning the crystal on my latest batches of boards, I found that I was receiving ASSERT_WARNING in lld_sleep_compensate_func()
// If this Assertion hits then the LP ISR lasts longer than the time
// that has been reserved via LP_ISR_TIME_XTAL32_CYCLES and LP_ISR_TIME_USEC.
if (sleep_lp_cycles && (sleep_lp_cycles < slp_period))
ASSERT_WARNING(0);
active RFID
Hello, Any reference code for active rfid?
Any advice how to achive to develop active RFID based on DA14531/DA14530.
Best Regards!
DA14531 dual role
嗨Dialog!
Can DA14531 act as dual role device:
a) central and peripheral?
b) central and observer?
