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

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...
We plan on use the ST BAL-NRF01D3 balun for a PCB with both an nRF51822 and a nRF51922 on the same PCB separated by about 4 inches.
Should we use the PCB antenna as on...
Hello.
I am very confused with memory layout of nrf51822 BLE examples using SoftDevice stack.
Some examples set IROM1 range from 0x0 to 0x3ffff. (ex, ble_app_advertiseing...
Hi,
