<p class="MsoNormal">Hello All,<o:p></o:p></p>

<p class="MsoNormal">I am using Quectel UC20 mini PCIe modem on my development board and running ModemManager on it. Since ModemManager is using by default baud rate set to 57600 I have decided to move to the latest version of ModemManager (1.7.0) since there
is a possibility to set udev rule for baud rate ENV{ID_MM_TTY_BAUDRATE}=”115200”. However after rebuilding ModemManager version 1.7.0 for ARM architecture and running it on my development board I have got the following error:<o:p></o:p></p>

<p class="MsoNormal">The only stable version of ModemManager which runs on my development board is 1.4.0. But when using that version I need to set Quectel UC20 modem baud rate to 57600 using AT+IPR=57600 command. I would like to take advantage of ModemManager
version 1.7.0 but unfortunately I am getting the above error while running it. <o:p>
