HL7800 "AT=KTCPSTAT?" , "AT=KTCPSTAT=session id" always returns ERROR

I am using HL7800 with AT&T sim. modem FW version is M.1.7.15. All the AT commands seems to be working. Network connection and cloud connection seems to be fine.

However, “AT+KTCPSTAT?” and “AT+KTCPSTAT=session id” always returns ERROR.
This AT command should return the socket status and the number of received bytes in the modem rx buffer. Socket is opened and running as I am able to connect to AWS and publish packets through MQTT.
Could this be an issue with the modem firmware?
Please find below the modem response for “ATI9” command -

Hi @sooraj.valappu

The KTCPSTAT command has not been implemented on firmware 1.7.15 HL7800 yet.
Please upgrade your HL7800 to the latest firmware to use this command.

You can get it here: https://source.sierrawireless.com/resources/airprime/software/hl7800-firmware/hl78xx-firmware/#sthash.26aty0qJ.dpbs
