I am using Ublox evaluation kit with SARA-N210. The factory set baudrate is 9600 and I am trying to change it to 115200 with at+natspeed=115200, but it immediately goes back to 9600.
I read through the manual, and it says that to store at+natspeed settings, one needs to do this:
SARA-N2
- The module must enter in any of the following mode:
o Enable the Power Saving Mode (PSM) by means of the
+CPSMS
AT command
o Reboot the module reboot by means of the
+NRB
AT command
But this doesn't help. What are the exact steps to store the new baud rate value into the NVM and make it persist?
This knowledge pertains to the SARA-N300 but as this is the next gen modem it probably also holds for the N2.
It will never work, the modem is just incapable of working at higher speeds. I know this because of an interaction with UBlox support. I couldn't connect using their tool and they were like: "oh yeah, that one can't run at that speed".
