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...
Hi, Nordic:
I'm testing the DC/DC function as to reduce the radio current. I have done the DC/DC test using pca10028 DK with the code below (SD v2.0.1, SDK11) :

Any idea as to the cause of this? What is the best way to debug this?
I am...
Hi,
I am wondering why PSTORAGE_NUM_OF_PAGES is by default set to 2 in the DFU project.
From what I understand the pstorage_raw.c module is used to update bootloader...
In iOS, it is possible for different apps to send data to the same characteristics in the same device by calling retrieveConnectedPeriphrals… Is there a way to identify the...
Hello,
currently, I am trying to get the SPI (master with EasyDMA) to work. I interfaced it with an LED driver IC , which needs some signaling (via GPIO pins) along with...
Hi,
I'm using the nrf52 board with sdk11.
I want to know that i have 100 beacons and my nrf52 is a cenral.
1)How many beacons can scan by the central at a time?
2...
Hi, I have managed to get my nrf51822 DK kit to read LDR sensor values. However the characteristic values are represented as hex on the master control panel and also on the...
Hi,
I'm i'm sniffing the NRF51822 s110, using the Nordic's BLE sniffer (on s120).
The BLE device is in a connection, and do a connection parameter update to a new interval...
Hi All,
I'm trying to update the application firmware of an nRF52 board with OTA DFU.
I have managed to create a .zip package (under linx, gcc compiler, Nordic SDK11,...
I want to make a program for wireless accelerometer with a microcontroller "nrf51822". I prepared the code however I face a problem with the ".h" files such as "nrf_error...
Hi All,
I'm having trouble running one of my I2C sensors connected to the nrf52 when running at a 200hz sampling rate.
Interestingly enough, the same sensor seems to...
I mean what kind of header information and stuff besides the data. I could only find this for advertising packets.
A graphic or list like this would be nice:
byte 0...
Hello,
I'm currently working on profiling an embedded application on an nRF52 using the S132 SoftDevice.
I've found that the svcall sd_softdevice_enable takes approximately...
