AT Command timeout
Posts: n/a In the software manual of my GSM module, I read that the time-out for commands such as: "AT+COPS", "AT+CLIP", "AT+CLIR" is 180 seconds Is it normal? Are there any faster modules? TIA Guy  Responses to "AT Command timeout"

Commands which take a lot longer include "AT+COPS=?" (which scans for available networks), and especially the rarely implemented "AT+CBAN" (which allows you to specify which GSM band you want the device restricted to). John
