Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.

Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino

Hi,
I referred to the sample code "led_radio_example" and I think I might miss some thing so the program does not work.
The sample code indicates to use a terminal program...
Hi,

Nordic will release a new development kit in april, named mkit.
It is based on arm mbed .
Writing a ble app will be easy, fast and simple using mbed BLE API .
My question...
Hello,
I compiled the pc10001/blinky_example with gcc/makefile, i can flash it with nRFgo Studio and it works. But if I try to compile/flash the pc10001/button_radio_example...
My computer is running KEIL MDK4 and nRF51 SDK4.
So far no problem with nRF51422QFAAC0.
Upgrading to Keil MDK5 would be a nightmare, so that I gave up after a few days...
Hi,
I'm trying the nRF UART example but I can't get it to work.
I have opened the uart_example project in uVision and loaded it to PCA10001.
Then I opened the Master...
I want to add timer to send sensor movement data to PC every 8ms(125HZ).
But when I add app_timer like normal
1.raise APP_TIMER_MAX_TIMERS
2.raise APP_TIMER_OP_QUEUE_SIZE...
I am testing Keil MDK5 and created my own simple nRF51422 project (not from the sample), hello world type of code. But the "download" button is disabled.
The J-Link is configured...
Hi,
Can anyone please tell me the exact way to enter into the bootloader mode by writing some characteristics with specific value.
I tried setting
NRF_POWER->GPREGRET...
The existing Master Control Panel cannot be used as an automatic test platform.
Basically I am looking to send commands via a tcp/ip which will invoke scan/connect/disconnect...
I'm trying to measure a scaled down battery voltage level on an ADC pin. Given my resistor values the voltage on the pin should be about 0.279 times VBATT, to fit within 1...
Hi Nordic guys,
How much is the current consumption of the LDO only (quiescent current), without DC / DC converter, in uA? How much is dropout voltage and PSRR (ripple...
