So I created an app based on [sms sample code](https://github.com/legatoproject/legato-af/tree/master/apps/sample/sms) to simply just receive SMS text messages. However, when the app is up, I don’t think the app console out any text messages in the log. ``` Jan 6 05:43:59 swi-mdm9x28-wp user.info Legato: INFO | smsReceiver[7351]/smsComponent T=main | smsReceive.c _smsComponent_COMPONENT_INIT() 93 | Start SMS app Jan 6 05:44:01 swi-mdm9x28-wp user.err kernel: [19278.578761] i2c-msm-v2 78b8000.i2c: NACK: slave not responding, ensure its powered: msgs(n:2 cur:0 tx) bc(rx:2 tx:1) mode:FIFO slv_addr:0x55 MSTR_STS:0x0c1300c8 OPER:0x00000010 Jan 6 05:44:01 swi-mdm9x28-wp user.err kernel: [19278.593902] i2c-msm-v2 78b8000.i2c: NACK: slave not responding, ensure its powered: msgs(n:2 cur:0 tx) bc(rx:2 tx:1) mode:FIFO slv_addr:0x55 MSTR_STS:0x0c1300c8 OPER:0x00000010 Jan 6 05:44:03 swi-mdm9x28-wp authpriv.info dropbear[7358]: Child connection from 192.168.2.3:30419 Jan 6 05:44:03 swi-mdm9x28-wp authpriv.notice dropbear[7358]: Auth succeeded with blank password for 'root' from 192.168.2.3:30419 Jan 6 05:44:03 swi-mdm9x28-wp authpriv.info dropbear[7358]: Exit (root): Disconnect received Jan 6 05:45:38 swi-mdm9x28-wp user.info Legato: INFO | modemDaemon[2277]/le_pa T=main | pa_sim_qmi.c InternalSimToolkitHandler() 1628 | QMI_UIM_REFRESH_COMPLETE_REQ_V01: Err 0 resp 0 Jan 6 05:45:38 swi-mdm9x28-wp user.warn Legato: -WRN- | modemDaemon[2277]/le_pa T=unknown | pa_sim_qmi.c UimStateChangeHandler() 1494 | No SIM application is in READY state Jan 6 05:45:38 swi-mdm9x28-wp user.warn Legato: -WRN- | modemDaemon[2277]/le_pa T=SimStateChangeEventThre | pa_sim_qmi.c MapSimState() 1009 | More than one application 2 Jan 6 05:45:39 swi-mdm9x28-wp user.warn Legato: -WRN- | modemDaemon[2277]/le_pa T=SimStateChangeEventThre | pa_sim_qmi.c MapSimState() 1009 | More than one application 2 Jan 6 05:45:39 swi-mdm9x28-wp user.info Legato: INFO | modemDaemon[2277]/modemDaemon T=main | le_sim.c SimToolkitHandler() 1048 | Update SIM Card information after a refresh Jan 6 05:45:39 swi-mdm9x28-wp user.warn Legato: -WRN- | modemDaemon[2277]/le_pa T=main | pa_sim_qmi.c MapSimState() 1009 | More than one application 2 Jan 6 05:45:39 swi-mdm9x28-wp user.warn Legato: -WRN- | modemDaemon[2277]/le_pa T=main | pa_sim_qmi.c MapSimState() 1009 | More than one application 2 Jan 6 05:45:39 swi-mdm9x28-wp user.warn Legato: -WRN- | modemDaemon[2277]/le_pa T=main | pa_sim_qmi.c RetrieveSimApplicationType() 2171 | More than one application 2) Jan 6 05:45:39 swi-mdm9x28-wp user.err Legato: =ERR= | modemDaemon[2277]/swiQmi T=main | swiQmi.c swiQmi_CheckResponse() 849 | Sending QMI_UIM_GET_EID_RESP_V01 failed: rc=0 (), resp.result=1.[0x01], resp.error=3.[0x03] Jan 6 05:45:39 swi-mdm9x28-wp user.err Legato: =ERR= | modemDaemon[2277]/le_pa T=main | pa_sim_qmi.c pa_sim_GetCardEID() 3118 | Failed to get the EID Jan 6 05:45:39 swi-mdm9x28-wp user.err Legato: =ERR= | modemDaemon[2277]/swiQmi T=main | swiQmi.c swiQmi_CheckResponse() 849 | Sending QMI_PBM_READ_RECORDS_REQ_V01 failed: rc=0 (), resp.result=1.[0x01], resp.error=41.[0x29] Jan 6 05:45:39 swi-mdm9x28-wp user.err Legato: =ERR= | modemDaemon[2277]/swiQmi T=main | swiQmi.c swiQmi_CheckResponse() 849 | Sending QMI_DMS_GET_MSISDN_REQ_V01 failed: rc=0 (), resp.result=1.[0x01], resp.error=16.[0x10] Jan 6 05:47:14 swi-mdm9x28-wp user.warn Legato: -WRN- | posDaemon[2296]/le_pa_gnss T=unknown | pa_gnss_qmi.c PositionHandler() 1537 | Bad position indication Jan 6 05:48:40 swi-mdm9x28-wp user.info Legato: INFO | modemDaemon[2277]/le_pa T=main | pa_sim_qmi.c InternalSimToolkitHandler() 1628 | QMI_UIM_REFRESH_COMPLETE_REQ_V01: Err 0 resp 0 Jan 6 05:48:40 swi-mdm9x28-wp user.warn Legato: -WRN- | modemDaemon[2277]/le_pa T=unknown | pa_sim_qmi.c UimStateChangeHandler() 1494 | No SIM application is in READY state Jan 6 05:48:40 swi-mdm9x28-wp user.warn Legato: -WRN- | modemDaemon[2277]/le_pa T=SimStateChangeEventThre | pa_sim_qmi.c MapSimState() 1009 | More than one application 2 ``` ---
