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.

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...
I'm trying to implement an application where one board updates another board with Nordic's DFU service. I'm using the NUS client example as a basis to develop the BLE central...
Hello,

I want to encrypt advertisements using aes-ccm peripheral present on the nrf51 board. I am not using softdevice, instead I am generating my own packets and transmitting them...
Hi,
I want to check if the FW is properly loaded into the chip and the chip is locked. Reading APPROTECT hangs the chip even if SD is not enabled. I assume APPROTECT is...
Hello,
I work on application (written in C, compiled with GCC) which use pc-ble-driver 1.0 and nRF51822QFAC with the ble_connectivity (S130 v2.0.0) as BLE Gateway. I need...
Hi,
Anyone around that has good experience designing nfc antennas?
I'm in need of a pattern that is about 50% the size of the flex that comes with the nrf52 kit.
Doable...
Hi @ all.
I have a strange behaviour that I can't get rid of. But first some specs:

I am nrf51822 QFACA1 chip with s130 softdevice using nordic_sdk_11.
ble_connectivity example was not working and i am unable to do a scan from my application board.
Currently, it using the I2S at nRF52832.
I want to play the wave file,But can not play well.
So, I ask you for a check because there is the following question.
[Question...
Hi all,
I have just buy a product use nrf51822 chip, I tried to find out SWIO and CLK pin out to flash but can not. Device only has RX and TX pin for Uart function, so I...
Hi.

I want to make init packet because DFU need it.
To make init packet,
need master control panel.
I want to know how to get...
Hi There,
Is it possible to modify the number of BLE frames per connection interval (CI)? We are using nrf52832s and are only seeing one master request and slave response...
Hello,
can anyone tell me something about the security level of the connection like it is made in the Heart Rate Sensor Example. Is the connection encrypted or can everyone...
