I know that &quot;AT+CPMS&quot; checks the message storage space, so i can use this to determine when a new message has arrived - but i do not know which index number the SMS is stored at.<br />
<br />
I have to use &quot;AT+CMGR=x&quot; (where x is the index number) to check every possible message index.<br />
<br />
&quot;AT+CMGF&quot; will list all messages - but takes far to long (typically about 20 seconds).<br />

How can i identify which index number a new SMS message is stored at.

SMS AT commands - how can i identify when a new SMS message is received, and which index number the message is stored under.

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
