I am using VirtualWire library ( http://www.open.com.au/mikem/arduino/VirtualWire.pdf ) and RF transmitter/reciver to communicate between two arduinos. There is function in this library to send data: vw_send((uint8_t *)msg, strlen(msg)); I need to send data like this: string timestamp; float volt…

VirtualWire send multiple variables at once

Is there any solution for this problem?

Of course. The sprintf() function comes to mind.
