I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
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...
Hello,
I wonder how power failure comparator works at VDD 2.1V.
If VDD goes down to 2.1V, and I set POFCON enabled at 2.1V threshold, then does POFWARN work?
How 2.1V...
Hi,
I am working on testing this modification on the ble_hrs example.
The idea is to send data sequentially as notifications.
However, BLE_EVT_TX_COMPLETE seems to...
Good morning
I use the fds function to store and read data in flash memory.
FDS_SUCCES is not returned by the fds_record_find function when reading data, so the read function...
Currently developing on NRF52 sdk12
I want to be able to show time stamp minutes:seconds:miliseconds on my RTT viewer, when I print my data out from the uC. Any hits on...
hello
i am using nrf52840, with BME280, i have external pullup 10k resistor.
how i can disable the internal pullup resistor.
i am using this sample code.

Hi,
I am having problem with setting up TX side of my project. It always giving me max_rt error if I am sending only once per cycle. 1 Cycle is every 30seconds. All working...
Hi,
I use the SDK12.3 and SD130 with secure_bootloader and my own application. I can flash SD and Bootloader and update my app over OTA with DFU from NRF Toolbox. My app...
I noticed that when upgrading to the latest Thread SDK that my devboard stopped booting. I was following the instructions as per the documentation but noticed that my user...
Hi,
I am designing a custom PCB using the nRF51422. I want to include an external 16 MHz crystal oscillator to use as X1 according to the reference layout for custom PCBs...
When I test the timer example with nrf52832 DK, it so nice to 4 minutes.
uint32_t time_ms = 240000;
But when I set the time interval over 5 minutes, then the event...
What is the maximum number of bond table entries a device can have?
If a device allows only one connection to be established at once (not more than one simultaneously)...
Hi,
I want to store the CRC of the current firmware in the flash, for DFU purposes. Almost all of the threads I've seen so far reference the pstorage API but it's no longer...
