Hi, I wanted to ask a question regarding sending data.
I currently have external memory that will send out serial data (SPI) to the nordic microcontroller. I have saved...
Working through a custom security implementation. It is to desirable to know a unique identifier for each bond that has been made with the nrf51822 SD. When the SD enters...
I have several asynchronous аperiodic sensors with their interrupt handlers. My service should gather the data from those sensors and do some math. The outcome of this math...
Dear all,
I tried to program and test the iBeacon application on the s110 folder from nordic examples.
The code on the Cortex-M0 has problem. Seems during programming...
After program nrf51822,it works normaly.But when I program again,it can't debug.NO SWD and NO USB DEVICE.So I can't use nrfGoStudio or nrfjprog.exe to recover it.When I pull...
Hi,
I've set up a streaming solution that is easily streaming 4+kBytes/s to an iPhone. I've also set up an ADC service that is sampling at 2,083 Hz 10 bit mode, using a...
Hi,
I am using nrf51822 (128k).
Softdevice 6.0 (s110), SDK 5.2.
How can I send an empty notification packet (data length 0) to master device?
If I send a packet with data...
I was wondering whether it is safe to use a delay (such as implemented by nrf_delay_us) to, for example, delay an iteration of a while loop, or that it is always better to...
Dear Sir/Madam,
I am testing iBeacon application on the nRF51822 mounted on nRF6310 motherboard.
I programmed the ble_app_beacon application in the keil_v5\ARM\Device...
