Difference:
GPIO4 and GPIO5 only support the read operation in SIM800H, SIM800L, SIM800,
SIM800M64 and SIM808.
SIM800, SIM800M64 and SIM808 do not support GPIO1.
21.6 AT+SJDR
Jamming detection PIN takes effect only in SIM800H, SIM800L, SIM800, SIM800M64 and
SIM808.The Jamming detection PIN is defined as follows.
Module Type Jamming detection PIN
SIM800H/SIM800L PIN5
SIM800/SIM800M64 PIN67
SIM808 PIN63
SIM800V, SIM840V, SIM800W, SIM840W, SIM800W16 and SIM840W16 have no jamming
detection PIN to indicate JD status, only report jamming status via URC from serial port.
21.7 AT+CREC
Play in call support AMR format in SIM800H, SIM800, SIM800M64 and SIM808.
The value of parameter <inputpath> is only
"0" in SIM800 and SIM800M64.
