SARA-R4 / SARA-N4
Saving AT commands configuration is not supported.
B.4 Estimated command response time
After having sent a command to a u-blox cellular module, the time to obtain a resulting result code depends
on the SIM and the network. It is possible to have an immediate response if the command does not interact
with either the network or the SIM.
The following table reports the maximum time to get the result code for the AT commands. The commands
are grouped by categories.
