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...
In my code, I have some 'print'-style functions that write data to a buffer, and that buffer then goes to the Nordic UART implementation. This is user code, and I don't know...
Hi, I'm trying to adapt the stm32f4 library from:

to run an nrf24l01+ with an stm32f373. After some initial SPI headaches, a lot is working. In the initialisation...
I want to confirm how much current is being drawn from the battery while the nRF52 is in it's absolute lowest power state and waiting for an NFC field to wake it up. From...
I am interested in setting the tx power level the advertising packets in a nRF52832 are transmitted with. I saw there is the TXPOWER register in the RADIO section (address...
I have a use case where sensors on a BLE peripheral need to push notifications to a BLE central indeterministically. So it needs to keep the connection always on. The notification...
Hi,
I tired Nordic Uart Service example on Nexus 5 Android ver 5.1.1, but I am not able to connect. I am able to connect to Samsung S6 and Nexus Android ver 4.4.4. I am using...
Hi Nordic,
I've try many times but no luck, I have a PCA10028, which works fine with SDK8~10 and S110.
Recently I found the SDK has become ver11 and SD turn to S130. So...
What is the best method for sending long data to ble_app_uart from android? We tried sending data by breaking into 20 bytes chunks and used thread.sleep() between each packet...
When I'm using the SDK 6.1.0, the twi drivers works while and I can easily understand the twi work flue. Howeve, the SDK 11.0.0 changed the twi drivers. I don't know what...
Hi Nordic,
I am using PCA10000 v2.2.0 with MCP and FW "MEFW nRF51822 0.11.0"
I just tried the "nRF Connect" under Windows 10 and fail to use it. Below is my steps:

Hi All,
I'm using nrf52 PCA10040 v 0.9.0, with SDK11. No softdevice being used in this case.
While exploring using EasyDMA with the SPI peripheral, the example in sdk11...
Hi there,
this problem may extend the scope, as it relates the SPI slave device (atmel winc1500). When I run the SPI master example, I can see the data transmitted on oscilloscope...
Hi, I use S110 v8 in my application with DFU support. When DFU is triggered from application (by writing 0x0104 to DFU service control characteristic), then application fails...
Working on a project i want to update the nordic application (firmware) from other MCU, i am having some problem to compute the crc.
How to we calculate the crc of...
