Table 16: TOBY-L3 series modules GPIO custom functions summary
1.14 Reserved pins (RSVD)
TOBY-L3 series modules have pins reserved for future use, marked as RSVD. They must all be left
unconnected on the application board.
1.15 System features
1.15.1 Network indication
☞ The Network indication feature of TOBY-L3 series modules is disabled by default, it can be configured
in different working modes(see Table 17) through AT command. For details, see the TOBY-L3 series AT
Commands Manual [2].
TOBY-L3 series modules provide the Wireless Wide Area Network status indication as described below:
 No service (No network coverage or not registered)
