I just started to interface the lcd display with nrf51822 evaluation board. The display i'm using is, spi compatible, 18" tft (160x130) from tiny lcd. I took spi master...
Hi,
We are using the nRF905 device in an application where it needs to switch between auto-retransmitting and sending single packets, due to it communicating with several...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hi,
I'm trying to see what the communication range would be for different transmission powers. I set the transmission power to 0 dBm, and observe that I can still receive...
I'm currently trying to make my application enter into sleep mode, after some search , I found that this function can be used to reduce the power while the chip is in the...
Looking over documentation and the forums, it appears that the softdevice is not meant to be used with an application that uses an RTOS. I say this primarily because disabling...
