| | 16 | == Antenna |
| | 17 | |
| | 18 | The following antenna was used for all certifications. Other antennas can be used if they meet the same requirements: Atel-Cab T-AT305, antenna gain all bands 2.14dBi. See info here: [https://www.atel-antennas.eu/wp-content/uploads/2017/01/T-AT305.pdf Link] |
| | 19 | |
| | 20 | == Certifications |
| | 21 | |
| | 22 | * Verizon Certifications |
| | 23 | * CATM1: [https://opendevelopment.verizonwireless.com/device-showcase/device/31073 Link] |
| | 24 | * CAT4: [https://opendevelopment.verizonwireless.com/device-showcase/device/31072 Link] |
| | 25 | |
| | 26 | * ATT Certifications |

| | 31 | == Drivers |
| | 32 | |
| | 33 | All drivers should already be included on Gateworks default Ubuntu builds on Gateworks SBCs. |
| | 34 | |
| | 35 | Drivers: |
| | 36 | * option (at commands), cdc_ether (wwan) |
| | 37 | |
| | 38 | == Modes |
| | 39 | |
| | 40 | The modem can be configured to be in different modes. Mode 0 states in a manual that it cannot be used for data traffic. |
| | 41 | |
| | 42 | Mode 3 works with data traffic and can be changed with AT commands to /dev/ttyUSB1: |
| | 43 | {{{ |
| | 44 | AT#USBCFG=3 |
| | 45 | AT#REBOOT |
| | 46 | }}} |
| | 47 | |
| | 48 | Another modem configuration that may need to be looked at is called FWAUTOSIM, which is automatic carrier switching by SIM. For this example, FWAUTOSIM was 0, meaning no automatic switching. |
| | 49 | |
| | 50 | == Software / Getting Started |
| | 51 | |
| | 52 | lsusb should show: (may change depending on variant) |
| | 53 | {{{ |
| | 54 | ID 1bc7:110b Telit Wireless Solutions Telit ME910 |
| | 55 | }}} |
| | 56 | |
| | 57 | Verify the modem is detected with the lsusb command. Then use modem manager to bring the modem up with the following example: |
| | 58 | {{{ |
| | 59 | mmcli -m 0 # Look for a large output of information about the modem |
| | 60 | mmcli -m 0 --enable |
| | 61 | mmcli --modem 0 --simple-connect="apn=hologram" #replace hologram with actual APN for SIM used |
| | 62 | dhclient wwan0 |
| | 63 | }}} |
