Server -> Client communication fmb64X

Hi,

i need some help.

Working:
setup: client with rs232 connected to fmx125.
Mode tcp/udp binary bufferd, timestamp enable, CMD ID 6, codec 12/13 merge disable.

Every thing is working. I can send rs232 data from client to server and i can send data from server (codec 12, cmd id 14) to client. i can send gprs command to fmc125 box with CMD ID 5.

Not working Setup:
FW:02.02.17

i only changed to fmb64x box. Starts with reset config. Enter APN und server IP, goto rs232/rs485.
COM1: TCP/UDP Binary Buffered, timestamp enable, Device IMEI disable, CMD ID 6.
i can send data from client to server.
The same Server returns a message ( working with fmx125) to the client, but the client will not receive it.

In the “Capture log” i can see both massages RX/TX but the RX message is not forwarded to the client.

The Acsii buffer mode do the same.

here is my log:

SOC0.TX:[00000000000000140d01060000000c69f9e399fd010203040404fe010000fe3f]

is this a configuration problem or need the FMB64X an other CMD ID ? i tested ID 1-14 with no success

maybe someone has a hint for me

Good Day,

The configuration settings appear to be correct.

At this stage, further investigation would require analysis of the device logs to determine the root cause of the issue. Kindly contact your Sales Manager so they can assist you with creating a Partner Portal ticket for further technical review.

Thanks, and best regards,
