- The required UART driver has been distributed as part of Linux kernel since v4.4.132.
- Check whether the required kernel module is loaded:
lsmod | grep option. - Check whether you have read/write access to USB-UART bridge:
ls -la /dev/ttyUSB*. - Download NB | EASY jar-file from Software & Drivers for Vodafone LPWA Products.
- Start the program via command line: java -jar Vodafone-NB-EASY-x.x.x.jar

| Parameter | Description | Definition | Example Value | Acceptable Range |
|---|---|---|---|---|
| RSSI | Received Signal Strength Indicator | RSSI is a measurement of the power present in a received radio signal | -67 dBm | -113 dBm..-51dBm |
| PCI | Physical Cell Identidy | PCI is an identification of a cell at physical layer. It has similar role as Primary Scrambling Code of UMTS cell.This physical cell ID is determined by Primary Sync Signal and Secondary Sync Signal. | 212 | |
| EARFCN | E-UTRA Absolute Radio Frequency Channel Number | EARFCN is a unique number given to each radio channel within the frequency bands used by the network . It can be used to calculate the carrier frequency | 6374 | 0..65535 |
| RSRQ | Reference Signal Received Quality | RSRQ is a C/I type of measurement and it indicates the quality of the received reference signal. The RSRQ measurement provides additional information when RSRP is not sufficient to make a reliable handover or cell reselection decision. | -3 dBm | -3..-19.5dBm |
| RSRP | Reference Signal Received Power | RSRP is the average power of Resource Elements that carry cell specific Reference Signals over the entire bandwidth. It is the average received power of a single RS resource element. | -76.4 dBm | -140 dBm..-44 dBm |
| TAC | Type Allocation Code | TAC is the initial eight-digit portion of the 15-digit IMEI and 16-digit IMEISV codes used to uniquely identify wireless devices. | AB7D | |
| MCC | Mobile Country Code | MCC consists of three decimal digit and it is used to identify the country. The first digit identifies the geographic region . | 262 | consists on 3 decimal digits |
| MNC | Mobile Network Code | MNC identifies the home PLMN of the mobile subscriber. The length of the MNC (two or three digits) depends on the value of the MCC. | 02 | consists on 2 or 3 decimal digits |
| Assigned T3412 | Assigned Timer 3412 | The periodic tracking area update timer to periodically notify the availability of the UE to the network. The procedure is controlled in the UE by (timer T3412). The value of timer T3412 is sent by the network to the UE in the ATTACH ACCEPT message and can be sent in the TRACKING AREA UPDATE ACCEPT message. The UE shall apply this value in all tracking areas of the list of tracking areas assigned to the UE, until a new value is received. | 4h | 0..35712000 sec |
| Assigned T3324 | Assigned Timer 3324 | The T3324 active timer determines the duration during which the device remains reachable for mobile terminated transaction on transition from connected to idle mode. The device starts the active timer when it moves from connected to idle mode and when the active timer expires, the device moves to Power Saving Mode | 6s | 0..11160 sec |
