☞ See the SARA-R5 series data sheet [2] and the +USIO AT command description in the SARA-R5
series AT commands manual [1] for the description and the USIO variant 0/1/2/3/4 configuration.
☞ After changing +USIO variant from 0/1 to 2/3/4 (or vice versa), the module needs to be switched
off; then, after changing SW401 according to Table 6, the module can be switched on again.
Run an AT terminal application (e.g. the u-blox m-center tool) selecting an AT port, with these
settings:
o Data rate: 115,200 bit/s
o Data bits: 8
o Parity: N
o Stop bits: 1
o Flow control: HW
See Appendix A for how to configure the u-blox m-center AT terminal for Windows.
8. To switch off the EVK-R5, send the +CPWROFF AT command. Make sure to use this command
before switching off the main power, otherwise settings and configuration parameters may not
be saved in the internal non-volatile memory of the cellular module.
