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...

Dear
As far as I know, the nRF51822 has the Pin Crossbar feature that weu can chose and connect
any GPIO pins as second UART.
I need to talk to two UART peripherals...
Hello Everyone,
I have created an schematic for m custom prototype using NRF51BLE with Sigfox Radio chip whenever i press the button on the NRF51i has to send message to...
Hello,
is there a trick, how the Radio peripherals device address match feature could be used to implement those advertising filter policies that filters based on the PDU...
I want to program the ARM MCU in the nRF51822 Development Kit for my own purposes and then send the processed data using the BLE module in the kit to another nRF51822 Development...
