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 all,
I use the example of examples/ble_central/ble_app_multilink_central/ to test the connect timeout event. When it scan the peripheral and try to connect it, power off...
Hi, I am wondering why, sometimes, I get an odd packet out of order on the receiver. It is very random, it can occur at anytime, though usually it takes a minute or two. Testing...
So, does anyone have practical advice for reducing the code size of peer_manager and related modules, so that the ble_app_template project fits on the nrf51822 128KB part...

Hey,
I'm currently doing the relay example on the nordic info centre.
I'm trying to manipulate the example so that I can transform it into a range extender.
The goal...
Upon testing I am seeing some slowness in setting up the SPIS DMA buffers for the next transaction. I perform a SPIS transaction, and then call nrf_drv_spis_buffers_set()...
