System mode: LTE PS state: Not attached LTE band: No band LTE bw: Unknown LTE Rx chan: 65535 LTE Tx chan: 6553 but if I recall the AT command regulary a have this : System mode: LTE PS state: Not attached LTE band: B20 LTE bw: 10 MHz LTE Rx chan: 6400 LTE Tx chan: 24400 EMM state: Deregistered Attaching RRC state: RRC Idle IMS reg state: No Srv RSSI (dBm): -67 Tx Power: 0 RSRP (dBm): -94 TAC: E487 (58503) RSRQ (dB): -9 Cell ID: 009CA404 (10265604) SINR (dB): 6.4 5 seconde after : at!gstatus? System mode: LTE PS state: Not attached LTE band: B7 LTE bw: 20 MHz LTE Rx chan: 3350 LTE Tx chan: 21350 EMM state: Reg Initiated Waiting for NW RRC state: Waiting RRC Cfm IMS reg state: No Srv RSSI (dBm): -83 Tx Power: 0 RSRP (dBm): -113 TAC: E487 (58503) RSRQ (dB): -10 Cell ID: 0624943D (103060541) SINR (dB): 4.4 and 5 secondes after LTE band: B3 LTE bw: 10 MHz LTE Rx chan: 1501 LTE Tx chan: 19501 EMM state: Deregistered Attaching RRC state: RRC Idle IMS reg state: No Srv RSSI (dBm): -79 Tx Power: 0 RSRP (dBm): -114 TAC: E487 (58503) RSRQ (dB): -9 Cell ID: 0927EF03 (153612035) SINR (dB): 5.6 and back to No Band. System mode: LTE PS state: Not attached LTE band: No band LTE bw: Unknown LTE Rx chan: 65535 LTE Tx chan: 65535 EMM state: Deregistered No Cell RRC state: RRC Idle IMS reg state: No Srv RSSI (dBm): -79 Tx Power: 0 RSRP (dBm): -114 TAC: E487 (58503) RSRQ (dB): -9 Cell ID: 0927EF03 (153612035) SINR (dB): 4.4 I think that i have a probleme with reception , it's normal that Cell ID change each 5 secondes ? for information the operator antenna is at about 100 meters only from the equipement antenna. in previous message I have this on <pre>> qmicli -d /dev/cdc-wdm1 --nas-network-scan : > Network [0]: > MCC: '208' > MNC: '10' > Status: 'current-serving, home, not-forbidden, preferred' > Description: 'SFR' ..... </pre> if the network scan report , this will assume that I can use the network ? It's normal that I dont have umts signal ? ( I try to force umts ) : qmicli -d /dev/cdc-wdm1 --nas-set-system-selection-preference='umts' then no more signal : qmicli -d /dev/cdc-wdm1 --nas-get-signal-strength [/dev/cdc-wdm1] Successfully got signal strength Current: Network 'cdma-1x': '-128 dBm' Other: Network 'cdma-1x': '-128 dBm' Network 'cdma-1xevdo': '-125 dBm' RSSI: Network 'cdma-1x': '-128 dBm' Network 'cdma-1xevdo': '-125 dBm' ECIO: Network 'cdma-1x': '-2,5 dBm' Network 'cdma-1xevdo': '-2,5 dBm' IO: '-106 dBm' SINR: (8) '9,0 dB' others info on another equipement (same hardware but not in the same place and only 3g on the area ) : Current Time: 67276 Temperature: 55 Bootup Time: 0 Mode: ONLINE System mode: WCDMA PS state: Attached WCDMA band: WCDMA 900 WCDMA channel: 3075 GMM (PS) state:REGISTERED NORMAL SERVICE MM (CS) state: IDLE NORMAL SERVICE WCDMA L1 state:L1M_FACH LAC: xxxxxxxxxx RRC state: CELL_FACH Cell ID: XXXXXXXXXXXXXXX RxM RSSI C0: -85 RxD RSSI C0: -106 RxM RSSI C1: -106 RxD RSSI C1: -106 no problem to get network and then connect , acces to the internet OK.
