Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
Hi,
I programmed the NRF51-dk to take ADC samples and transmit those values at 8 bit resolution. Now I want to send a 10 bit resolution value over BLE UART, but I believe...
Hi everyone,
In my low power application , I use PORT EVENT to detect the interrupts of my two pins.
when I use only one pin interrupt, it's working well .
But with two...
Dear All,
We are implementing 8 Pheripheral Nodes and one central node with S110 and S120 respectively.
We have our custom board with us we are able to connect the pheripheral...
