UART shuts down every 10 minutes

Dear All,
I ma using Q2687RD modules, i have enable both (UART1&2), when no data reception on both the uart port , module resets exactly at 10 minutes from restart, when there is a data on any uart it will work without any problems…

Kindly suggest what could be the problem…

Hi,

What’s the “data reception” mentioned? Is it running in CSD/GPRS data mode or with OpenAT running?
What’s the baud rate configured?
Can you also test with latest FW?

Thx

Hi,
below is the uart configuration on both the UART’s

9600,8,1,N ; we are using uart for analyzing external data( ascii format) with Open AT running,

i have tested with 7.47 version firmware;

Problem still persist …

Kindly suggest further…

Regards,
BR
