radiohead library related to lora shield having sx1272

I am using DRAGINO LORA SHIELD WITH ARDUINO (server) and SX1272 MBED SHIELD WITH ARDUINO (client) for node to node communication. I am using examples of Radiohead library for RF95 FOR CLIENT AND SERVER side. BUT I am getting
Sending to rf95_server
No reply, is rf95_server running?
AT server side i am not getting any output.
so radio head library is compatible with sx1272 mbed shield?
