I have a LED dimming project that uses nRF51822 and nrf_pwm_noglitch. If I turn to 100% duty cycle, then it will be stuck at 100% unless I turn it to 0%.
So in other words...
The board is simply an nrf51822 with a crystal and required caps and resistors, without any LEDs. When I try to flash any firmware, I get an OK that the firmware has been...
Hello guys,
I am working on the project where I am making a network4 nrf24l01 transceivers, such that one can broadcast the text message from one transceiver at the base...
Hi, I'm trying to write a long byte array with the nrf master control panel on android. I'm unsure if the app is able to, but in any case I'm not getting the event: BLE_EVT_USER_MEM_REQUEST...
Hi,
I have my custom nRF51822 board, and i used to flash the firmware through nRF51 DK kit.
As there are two ports through which we can load external boards i was using...
Hi,
I'm trying to build a prototype using the Adafruit nRF8001 Breakout and an mbed ARM CPU.
After Reset, I get a Device Started Event, telling me the chip is in Setup...

Hi,
Got stuck on an issue that has come and gone and then working fine, and are now back again.
I use a nrf51 module with the led-button-service example (sdk 5.2). It...
So, we are pretty far along in development (I have inherited the project) with an nrf51822, SDK 4.4.2 and SoftDevice "6.0.0-alpha". We are nearing release, and I was told...
I have set the POFCON to enable the power failure comparator and set the voltage level to2.5 volts. How do I know when the battery voltage is below the 2.5 volt level? How...
