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 think it's a simple question. I want to connect a micro to communicate with a phone via the nrf8001. I ported everything thanks to the guide that you posted (for...
Can we use the tx_complete.count given with BLE_EVT_TX_COMPLETE as an indication on how many packets were sent out from the last ended connection interval?
thank you
