On the project at present is to move far BC26 module for NBIOT communication, modulated, equipment can register, can report the information to the platform,

Now want to move far too BC260Y - CN module to replace the BC26 module, the manual is the pin to pin, directly replace the module, and did not move, hardware software only changed PWRS/boot,,
But BC260Y - CN has no reaction, the AT command also didn't reply,
