Question

Hi,

I'm trying to send commands to fmb640 device via TCP but, instead of receiving response to my command, I keep receiving AVL packets. The algorithm I use is the following:

1) Establish tcp connection 

2) Receive IMEI number from the device

3) Send command "0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x0F, 0x0C, 0x01, 0x05, 0x00, 0x00, 0x00, 0x07, 0x67, 0x65, 0x74, 0x69, 0x6E, 0x66, 0x6F, 0x01, 0x00, 0x00, 0x43, 0x12" (this is getinfo, as seen here https://wiki.teltonika-gps.com/view/Codec#Codec_for_communication_over_GPRS_messages)

4) Receive standard AVL packets instead of the response to my command

I've also tried to send 0x01 command and wait 5 seconds before sending my getinfo command, but it's still the same

Where am I doing the wrong step?

Thank you in advance
