I try to print the RSSI level but i couldn't do. I use nRF51 DK and soft device S130.
This is the line that i just write:
I don't need to connect the master with the peripherals, but i have to know how is the maximun quantity of scan response that can accept the master. In the example ble_app_multilink_central this is defined like that:
I want to program the BMD-300 with the nRF52 Preview Development Kit. I have connected:
BMD-300 -> nRF52-DK
SWDIO -> SH_SWDIO (pin #4) on P20
SWDCLK -> SH_SWDCLK (pin #5) on P20
VDD -> SH_VTG (pin #3) on P20
GND -> SH_GND_DETECT (pin ... (more)
I want to connect one board trough SPI to my nRF51-DK. Using SDK11 and SD130, the nRF51-DK is the SPI master, I call the function
nrf_drv_spi_transfer() but the CS Pin is never toggled. To solve this I changed it ... (more)
Hello, we have made cars that play laser tag against eachother using infrared emitters and receivers. The problem is that the infrared radiation bounces off the surroundings, and the cars end up getting hit by themselves.
The way it is ... (more)
