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.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
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...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
I tried changing the define below from 1 to 2, so I could have one handler for a button and a different handler for other sensors. But my problem is:
If I set it to...
Hello,
I've developed a circuit with Mikroelektronika's nRF T click module. This module uses nRF24L01P but as I see I cannot order it because it is obsolete.
Should...
We plan on use the ST BAL-NRF01D3 balun for a PCB with both an nRF51822 and a nRF51922 on the same PCB separated by about 4 inches.
Should we use the PCB antenna as on...
Hello.
I am very confused with memory layout of nrf51822 BLE examples using SoftDevice stack.
Some examples set IROM1 range from 0x0 to 0x3ffff. (ex, ble_app_advertiseing...
Hi,
I have a nRF51422-EK board (Rev. 1.0) that is bricked.
When connected the LD3 is on.
Jumpers are present on P8 and debugger.

Hello,
I was puzzled by RM.
I notice POWER control register in peripheral(UART,SPI,TWI) module.
Please answer following questions about the relation between system...
I download the softdevice for PCA10001. And I want download another program, but it didn,t work. The problem I have attached here. As you known, I have push the button 'recover...
We plan on using the external 16 MHz and 32 KHz oscillator inputs to reduce BOM costs since our host micro uses a 16 MHz and 32kHz crystal and it can generate outputs. If...
Hi guy:
I have buy nrf51822 dk .Why I can not download nRF UART App for Android 4.3 at below page www.nordicsemi.com/.../nRF-UART-2.0-for-Android-4.3
Thx
I made code like to below for using 16Mhz system clock.
/* Start 16 MHz crystal oscillator */
NRF_CLOCK->EVENTS_HFCLKSTARTED = 0; NRF_CLOCK->TASKS_HFCLKSTART = 1;

Hi guys,
I have designed a custom board with nrf51822. Data transfer seems OK, when I do it through Master Control Panel - I can write data to characteristics and I can...
Hello
I'm planning to use the nRF8001 SCC with an external microcontroller. So far we have purchased the nRF8001 sdk and the nRF6700 Started kid. My question is simple...
Hi All,
