TTGO T22_V1.0 lora module not working

recently i baught TTGO T22_V1.0 module and i have to use lora module for data transmission.
but the thing is that earlier i hav been using SX1276 module and now i want shift on TTGO, but i have only single end lora module .
so, what i did, i use one SX1276 and one TTGO module for communication. and this is nnot happening. if it could be the problem in SX1276, i have already used SX1276 module for transmission and receiver. and it was working fine.
then what should be the problem.
is it possible that i could not connect TTGO module with SX1276 .
please help me out.
thanking you .
