I need to be able to change the GAP parameters of my connection for only a short period of time to save battery life but have high throughput when I need it. My firmware...
Our workshop is using custom PCBs for other manufacturer's developer kits, and I'd like to do a similar shield for our nRF51-DK boards. Can anyone provide a KiCad project...
Hi all,
I took the example SPI program and I am trying to add UART code to it to debug the SPI transfers. Both examples are working well for me separately. I was able to...
I am working one one star network system with NRF24L01+. I got success with one pair (Single TX and Single RX) on communicating. But I could not get any positive result for...
Hi,
I'm working with an SPI FLASH chip that has a page size 256. I noticed that when I call nrf_drv_spi_transfer() , the rx length of 256 rolls over the uint8_t container...
Why the SPI clk doesn't work, i checked using an oscilloscope :/
I also don't get any SPI interrupt and no data change in the RX buffer although I have wired MISO and MOSI...
