I have an LX40 modem that is used in conjunction with WIN-911 for SCADA system alarming. I am able to send out SMS using the WIN-911 Workspace interface and also with QuickSMS in the LX40 interface, but no texts I send to the number are received as indicated by the “Last Incoming Message” readout under “Inbound SMS Messages.” I have included a screen grab of the SMS setup under Services->SMS. The cellular connection is fine and functioning as expected. Any idea how to troubleshoot the issue?
Hi @BrandoUSC,
Welcome to our community!
…but no texts I send to the number are received as indicated by the “Last Incoming Message” readout under “Inbound SMS Messages.”
According to description, I understand that even if you send an SMS command or send SMS messages from another device to the LX40, the LX40 does not receive any SMS, and no messages appear under ‘Last Incoming Message.’ Is that correct?
- Please make sure antennas are properly attached to LX40.
- What ALEOS version and radio firmware is LX40 running? If it’s not the latest version, please update to the latest and try again to see if the LX40 can receive SMS. Link: source.sierrawireless.com/resources/airlink/software_downloads/lx/lx-firmware-list/
- Could you please let me know which carrier’s SIM card you are using? Please ensure that the SIM can receive SMS without issues by testing it in other devices such as phones or tablets. Alternatively, you can try using SIM from a different carrier to check if the LX40 can receive SMS.
- Please provide log file and template file from LX40 and indicate the timeframe when you attempted to send an SMS message to the LX40 so I can easily check the logs.
Thanks,
