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...
How to run the sdk examples from usb on the Sparkfun. I can run the adruino code, but want to shift to a more standard production environment.
After manual install of GCC...
I can run the SAADC example and read the analog inputs fine, now I've modified the code to simply read the adc with the blocking nrf_drv_saadc_sample_convert call
All I...
Dear All,
while testing an own nRF52832-based PCB and an nRF5840 PDK for current consumption, I compiled and flashed the code below to both devices. Since then I am not...
Hello All,
I don't find any example of Dynamic Multiprotocol of ESB and BLE.
The current multiprotocol example in Nordic’s nRF5 SDK is a switching solution for multiprotocol...
Hello,
Here is a summary of my main transmission protocol:
The (unique) client contact one of the many servers to get the value of a particular server's state.
In the...

I have a couple of "cannot-be-resolved" issue with Eclipse.
Issue 1:
Sometime when I set up a project in Eclipse, it runs into an issue where types like uint32_t or...
Hi,
I'm trying to send sensor data via BLE to Processing. If someone has already done it, could you post your code or help me explaining how to approach the problem?
I...
Our Nrf51822 will disconnect the connection with timeout reason when it is sending a large amount of data (about 20-70 KB) to our central device which is TI cc2540 . This...
Hi Nordic.
I have questions about preserving device unique information such as device id and so on. (The information will be written in factory)
I know the best way is...
I am trying to add I2C/TWI bus to nrf51822 device. I have used the SDK example code (12.3.0) and keep getting the following errors:
sdk/drivers/nrf_twim.h:69:38: error:...
Hi, Is it possible to make the same nRF52832 device to function as a master for some interval and then switch it to slave?? i.e, Does Nordic have a single SoftDevice capable...
Hello, the current QIAA package is rather demanding on the manufacutring and significantly increases our cost, are there any alternatives? I failed to find any in the datasheet...
Hi !
My goal is to create a large mesh network (over 100 nodes).
I plan to have 3 kind of nodes : a client (connected to a PC), several server relay nodes (not on battery...
