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.
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...

Hi there, I have managed to set up my IDE and build environment so that I can build and download the example projects without any trouble, but have then spent the last two...
Hi.
I'm using SDK12.2.0, S130 ver2.0.1, nRF51822AC.
As I know SDK12.2.0 can conenct 8 peripherals at the same time when it is Central mode.
I want to use it as central...
I've got a custom NRF52 board that uses less than 4uA when sleeping without SPI but after the SPI is initialized (and then uninitialized) the current consumption rises to...
Hi Nordic,
For my application, I want to have the absolute acceleration (without gravity) from a MPU6050. I know that this device can do that because it has 6 axis and...
Hi,
I am trying to maintain a single bit of information through a power-on reset event (sd_nvic_SystemReset();). I am trying to do this through the configuration of an...
Hello,
I'm having problems running the DFU over serial bootloader example. The nrfutil command to update the application fails with message "timed out waiting for acknowledgement...
Hi together,
I'm trying to scan for BLE Beacons and I got the problem that if I set setReportDelay() to a value unlike zero, the onBatchScanResults() method is called and...
Hi,
I am trying to measure the current consumption on my application, and measured some quite high values even after calling sd_app_evt_wait().
After reading through some...
We have a product that uses nrf51422_CE_AA, Revision 3, 256KB ROM, 16KB RAM, PCA10028, SDK 8.0.0, S110. We have sold over 8000 devices of our first product. Currently we are...
Hello,
My problem is to much current c.a. 40uA in POWER OFF mode. Below attach code:

I am getting no radio (as in not being able to pick up advertisements packets) from my custom nrf52832 board. The antenna design is a hack so I am not looking fo stellar performance...
We are looking in to developing a generic class to connect and handle our BLE devices for use on mobile devices such as Android and iOS.
Now since we want to have as less...
Hello Experts,
I am running the following examples to test the DFU bootloader in gcc and eclipse environment.

I found a problem of the nRF51822 in boot state.
Power on reset is not executed occasionally when used dying battery.
The problem occurs in the following steps:
