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...
i made this project to try to create RSC service on arduino

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...
Hi
I want to know how to use ppi to wake up CPU from IDLE mode.
I've tried to use timer timeout event for triggering Port Event and wake up CPU, but can't assign NRF_GPIOTE...
I have been using a module of nRF52832. I write the Direct test mode in the module, to measure the current consumption of the Tx and Rx. DTM setting is + 4dBm, DCDC off. As...
Hello,
I try to send about 80kB of data between 2 beacons and I have encountered some problem that I got no idea how to resolve.
I have managed to connect devices, discover...
There are certain design decisions that break C++, or at least the separation of concern between allocation of entities and the use of entities.
For example:
typedef...
Hi there,
Is there any chance future SDKs with the nrf52 have support for Mifare Classic cards? The example with the Adafruit shows an Ultralight tag, but it would be useful...
I have a USB dongle with nRF24LU1+ chip (marking "NRF E LU1P16 1438AD").
I have several problems with programming this chip via SPI. For example after entering programming...
Dear Nordic developer：
I am very eager to have the "Android-nRF-Connect" of the source code! I found the scan and DFU from the "Android-nRF-Toolbox" function, I also need...
I'm trying to get going on an nRF51 project using the compiler on mbed.org, but if I create a new project using the nRF51 DK and use any of the example BLE apps as templates...
I am runing the example on custom board 16k ram, i have configured the linker file correctly as shown below. but all the ble_peripheral application doesnt run (not advertising...
I'd like to erase all the pages managed by FDS as part of a "Hard Reset" operation. fds.c has a hint of a "FRESH_INSTALL" directive (part of an enum defined in fds_internal_defs...
DEVICE_MANAGER_MAX_BONDS is no more than 10.
That means that no more than 10 difference devices (smart phones) can switch the device to DFU mode?? (with boding).
Am I right...

Hi
I cannot find the minimum pulse length to trigger wakeup using DETECT from GPIO hw pin configured as SENSE pin in the data sheet for nRF51822.
Ex: set PIN_CNF[0].SENSE...
