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.

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

when i download an example on my nrf and run it to see error check its not returning anything
in s110 i have error...
Hi, In my custom project I need to add two 128-bit uuid services and also I need to use pstorage to protect the application data from power loss. But I got the problem is...
Hi,
While working on OTA DFU using my custom code compiled to work on PCA10028 board, I am seeing the following issue.
The OTA DFU works fine using Master Control Panel...
Hi,
I'm designing an antenna for the NRF52 but with some different conditions, the antenna will be under a silicone superstrate and this will change the impedance of the...
Hi..
Everyone,
i am using nrf52 with softdevice 132.
i used peer manager.
i am able to able to flash softdevice, bootloader and application.
but after that application...
Hi,
I've built a device using an IMUduino board, which is supposed to be similar to Arduino Leonardo board with a nRF8001 bluetooth. I was able to connect my device to...
Hi all ...
My product uses multiple BLE peripherals (Simblee by RF Digital) communicating with a common BLE central to time events detected via sensors on the different...
Hi,
The situation:
I was able to successfully receive known packets from a device running gzp_device_dynamic_pairing, from, the host running the gzp_host_dynamic_pairing...
So the nRF51822 has one 32 bit, two 16 bit timers and two Real Time Counters.
What is the difference in a timer and counter? The timer API seems to hard link RTC1...
Hi,
In my project I am using nrfutil.exe tool to create a .zip by using the following command

I'm running into a weird problem where there is a long delay that is variable between calling ble_conn_params_change_conn_params() and receiving the BLE_GAP_EVT_CONN_PARAM_UPDATE...
Hello,
I've got a problem with my nRF51 DK. When I attach it to the USB port the drive doesn't appear on Windows explorer and green diode doesn't flash too.
I've been...
By design, the TI LP55231 LED driver IC will fail the TWI write of the reset register (0x3D). It's necessary to reset the IC in an edge use case. I'm using the nRF51822 HW...
Hi,
I want to write a characteristic, the value size is fixed, for example the size is 4 bytes. When I try to wirte 6 bytes from the client, the first 4 bytes is writed succesfully...
