    Wireless communication range problem

    Dear All, I am using nrf24l01 module for my wireless communication project with arduino .Problem is that The data transmit & recieve successfully only when line of sight is clear.if there any obstacle or wall in betwen them then signal strength is poor or fail to communicate.how to increase...

    ds1307 Rtc clock running slow by 6 second per day.

    Thanks for replies.First I have tried by diffrent retailers available locally,then i purchased online by rhydolabs(shows original ds1307 on offer).But issue not solved. I Read the application note.But sometimes in past it shows good accuracy in same design.
