Radio Transmitter/Receiver example

[cho jae young]

Your served radio tramsmitter/receiver example using PCA 10000 USB dongle, PCA 10001 evaluation kit. It's just only one byte data communication. It works well. If I communication multi-byte data with one packet, what did I fixed source code in "main.c" , "Radio_config.c"?

sir,

i am using Radio Transmitter example .i am able to send data successfully.but i observed current as 9.7mA constantly.

please help me to reduce power consumption.

here is  SDK: examples/Radio/transmitter
