Hello!
How can I communicate with my nRF24L01+ and nRF51822 at the same time. I can set up same channel, CRC-mode and I don't use ESB. But what about address? How do I set...
Hello,
I need to read by Battery Voltage using ADC. My Battery is 3.3v which is being stepped down to 2.1V using a LDO regulator. So my VDD is 2.1V in DC/DC mode.
Now I...
Hi guys I'm sending data from an nexys 4 fpga through an spi to my nRF51 (pca10028) I have the fpga set as the master and I'm able to read data sent to the nRF51 through my...
Hi.
I'm using nrf52 as slave for another device. I'm reading test string from the nrf buffer and I can see extra zero (rest of the content is then offset by one -> corruption...
