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...
I don't have a 32KHz crystal on my board (using the stock Rigado module) and power isn't an issue as the board is mains powered in operation, so I was intending on using the...
I found a alpha version of softdevice v3.0 (s132_nrf52_3.0.0-2.alpha.zip), and it supports MTU_SIZE > 23 bytes, but there is no SDK (current version is v11) supports it. When...
We have two nRF51822 chips with cleared contents in FICR, e.g. addresses 0x10000000 - 0x100000FF are 0xFFFFFFFF.
UICR works as expected.
Chips execute code.
Radio performance...

Hi
I'm looking for a functional example based on Freertos and nrf52 on SDK11 and SD132. I'm having problems (hard fault) and I've been looking for this example but with...
Hi There
I see there is a Proximity App - is this available for downloading like the beacon App ? for use in xcode ?
Also, in the demo, there was a bluetooth unit that...
I use a android phone as central(Master) and use a nrf51822 as a peripheral(Slave).
The peripheral can send the "L2CAP Connection Parameter Update Request" to change the...
Hi
I have a BLE nRF51822xxAA project created with Keil 5.15, SD 100 ver 802 and Family Pack 803.
I made a new configuration in a new machine with Keil 5.2 and I am getting...

Hi! I work with a smart Beacon Kit nrf51822 rev1.0.0, s110 and I have visualised my current consumption. What I expected to see is that my beacon could send in one time all...
We are preparing a project where several mobile phones
with Android OS in peripheral role will be connected continuously to
one nrf51822 with S130. Communication must be...
On nrf51 I was using:
pre flash: w4 4001e504 1
erase all: w4 4001e504 2\n w4 4001e50c 1\n sleep 100
pin reset: w4 40000544 1
Is it still the same for nrf52...

My application on a PCA10028 board is attempting to send a BLE advertisement using sd_ble_gap_adv_data_set() by going through ble_advdata_set in ble_advdata...
I'm trying to design a very low power sensor that takes readings using ADC and SPI 200 times a second. I'm a bit worried by the current EasyDMA uses (1.1mA). As far as I can...
Hi,
is there something like a makefile for nrf52 out there?
I want to use eclipse and gcc in osx. It worked great for nrf512 but nrf52 has other addresses and maybe...
