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...
Dear Nordic,
When testing the DFU process, I noticed something unexpected. We are using the secure DFU USB bootloader, with forced dual bank updating. I'll attach both the...
I am using ibeacon format for my device. The specification says to include the RSSI value calibrated at 1 meter in the payload.
Can you please tell me how to find out...
Hi,
We managed to integrate both normal BLE and mesh stack onto our working prototype, powered by nRF52840. So far, it is working well. We are trying to further maximise...
I am using the NRF52840 controller to connect BMD101(ECG sensor) uart based having a baud rate of 57600.
Note: Using UART peripheral example on SDK17
I am trying to parse...
Hi
I've problem on my design when I use voltage translator to communicate with sensors. Can you guys see pictures below:

Hi all.
I want to send my packets in the negotiated time interval.
I sat the NRF_SDH_BLE_GAP_EVENT_LENGTH to 6.
The negotiated TI is 36 ms.
the results are
1- the...
Hello to all,
(If "TLDR" go to "### TLDR ###" in the bottom of the page, where you'll find the straight questions without all the context... ) Me and my team are using the...
Hi,
I noticed that the value raw_uuid_len in function ble_advdata_uuid_find() in module ble_advdata.c is fixed at the value UUID128_SIZE.
So the function can only find...
Hi, I am new to NRF and segger embedded studio.
So I want to send temperature sensor data connected with nrf52840 DK to the Murata1_SC device using UART.
The data will...
Found a potential "weirdness" with the mergehex utilty. When merging hex files containing code, dont seem to have an issue. Recently I was using mergehex create a full programming...
Hello Team,
Can you please confirm if we can use the crypto API to do AES encryption/decryption. Can I use it in non secure app and in application and not in bootloader...
Hi,
We want to make some BLE application for nRF52840 on Thingy:91. Referring to PCA20035 schematic, there are some spare pins which we assume is available for GPIO as...
Hi, we have a product (NRF51 SD8 S110 RBCMesh) on the market that craches about once per year the line that asserts is line 189 in src\\soc_radio_timeslot.c (your code) and...
