AT Commands
AT command is very familiar with the legacy serial application developers. So, AT command interface
of Parani-SD eases a lot of efforts to develop their own application from developers. So does Parani-
MSP100. Moreover, AT commands of Parani-MSP100 are so similar to one of Parani-SD that
developers who have experiences with Parani-SD can make use of multi-serial functionality in no time.
