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...
Hi,
I am testing BLE throughput between NRF52832 and iPhone XR using S132 stack. I am able to get maximum of 400Kbps. Is there a way to achieve throughput better than...
Hi,
I am trying to design the transmission lines based on the reference board design from Nordic.
I opened up the Altium layout file for the board which I downloaded...

Hi
I want to use TWI read temperature from sensor Si7050, but i got a problem that doesn't jump into twi handler event. Can anyone give me some information? Thank you. ...
Hi,
This is somewhat tricky question..
Does GAP broadcaster differ with the BLE device which advertise packets with non-connectable option?
Is The device which operates...
I read the specifications on nRF51 series and the spec say that Bluetooth 4.2 with 2Mbps. However, standard Bluetooth 4.2 only support maximum 1Mbps bitrate.
First, I wonder...
So I added a header files folder to my project and then added a header file. The project would no longer compile after doing so. To troubleshoot, I changed everything in my...
Hello,
I am trying to upgrade my working projects to SDK15.3 from SDK15.2. All projects work except the bootloader project as there are significant differences in 15.3...
Hi,
If I understand corrctly, the flag CONFIG_NRF_CLOUD_PROVISION_CERTIFICATES=y should only be used once,
after that, the certificates are saved inside the modem.

Hello.
We are developing a device that require a 1Gb qspi memory interafaced with a nrf52840.
So far the qspi driver and the memory inits and the memory respond to some...
It appears that my watchdog timer is running during interrupts that are handled by the SoftDevice and do not cause a return from sd_app_evt_wait. This is described in the...
In migrating a project from SDK 14.2.0 to SDK 15.3.0, I'm also trying to move from the "legacy" non Easy DMA SPI driver to the Easy DMA one. I don't much care whether I use...
Hi,
I've been struggling with a problem with my builds for over a year now.
On some builds NFC works perfectly, but on many it doesn't - and I have no idea why. I can...
Hi, I'm having problems with proper softdevice reinitialization. What I'm trying to do is work out proper reinit solution - what I'm doing is enabling BLE_stack and all the...
