WiFly GSX doesn't forward data!!!!?????

Dear all,

I have a big problem with my WiFly shield…

I transmitted serial data by PIC18F4550 USART to WiFly UART…

The baud rate of the PIC and WiFly UART are tha same (9600, no parity)…

I connected Tx of PIC with Rx in WiFly shield… Tx of the PIC comes from 3.3 voltage divider circuit…

I ensured that the PIC was transmitting data to Rx in WiFly shield but WiFly didn’t forward any data to the IP host…

Notice that a TCP connection is established between the WiFly and the host, and the default “Hello” word appeared in the host

but the serial data from the PIC were not transmitted to the host…

Here are the image of WiFly shield circuit…

well this could be cause by many problems

but lets start with the simplest as it solved my problem

buffer may not be full enough to empty itself and forward the packets

there are 3 ways considering the buffer

it could forward through a timer or a flush size (default) or when a certain character is matched

so check these and refer to the wifly manual for commands on how to reconfigure it

Thanks for your reply

Flush timer size was set to its maximum size: 1460 bytes

but the problem is still…

I want (if you see the image of the connection) to know whether the connection is right or not???

Is there another pins must be connected (what about D10-D13 on the shield)…

Thanks
