I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...

I had a PWM question ( here ). It was recommended that I install SDK 10 and use the PWM files from SDK 10. I installed and copied the PWM files from 10 to 9 and opened my...
Hi, I've compiled program from this link:

The problem is that I can't connect to my DK by nRF UART 2.0 app, probably because not every UUID is...
I am working on adding a timer in the ble_app_uart sample, aiming on disconnect with device which doesn't send any data in specific time, such as 5 seconds.
Now I have...
I get NRF_ERROR_SVC_HANDLER_MISSING error in spi_open function.

hi,
I need to store persistent data of about 32 bytes in flash, so tried using pstorage APIs (SDK v9.0 on nRF51822 -- 256KB ).
I followed the sample code given here...
Hello,
I am using keil uvision 5.17, sdk 9.0.0 and sd 130.
Once I programmed whole application through mbed,
Then I moved into keil and implemented all function....
We are trying to communicate to NRF51422 through PC using UART communication. But the programs works fine with nRF51822 Dongle and DK. But it does not works with another dongle...
Hi experts,
I need nrf51822 to send thousands of packets (notification) to Master Control Panel (PC), and expect for high data rate. So, I turned the connection interval...
