1.5 AT command support
The LARA-R2 series modules support AT commands according to 3GPP standards TS 27.007 [7],
TS 27.005 [8] and the u-blox AT command extension.
☞ For the complete list of all supported AT commands and their syntax, see the u-blox AT
Commands Manual [1].

GPRS/EDGE multi-slot class determines the number of timeslots available for upload and download and thus the speed at
which data can be transmitted and received, with higher classes typically allowing faster data transfer rates.
6
GPRS/EDGE multi-slot class 33 implies a maximum of 5 slots in DL (reception) and 4 slots in UL (transmission) with 6 slots in
total.
