spwf01 module Timing Issue

Hi,

I observed followings while communicating between two

spwf01

modules:

At the Client side when its try to connect to server I’m using AT+S.SOCKON command to connect.
In this command I can pass “ind�? parameter which can indicate data arrival at the client side with “+WIND:55:Pending Data�? on UART interrupt .
Client side it is taking 500ms to receive WIND:55:Pending Data: interrupt.
Server to client data transmission it takes only 5 to 6ms.

Please suggest how to solve this time delay at the client side.

Thank you

Please post some other info: FW version, status dump, average RTT of the network, kind of socket used, etc...

Hi,

I have observed Station mode module is taking more time(40sec to 1minute ) to search the access point module.

How to reduce this time?

kindly give suggestion.

Thank you

Basavanagouda.

AT+S.STS also

As many info you can share, as fast we can solve...

ps: check your UART driver. you are loosing a lot of bytes. consider to use an rs232/usb converter at this early stage, removing external MCU.

version = 141106-0950875-SPWF01S

you are using a 2 years old release.

First of all, please update to FW3.5

Oops:(

Can you please share the latest version firmware and Updating procedure from UART.

It will help me lot.

Thank you

If I update the firmware version, above issue can be resolved?

it already took lot of my time to solving it.

Please let me, If its can solve my issue it will help me lot

Thanks

Try new FW and let me know.

E.g. FW3.5 works better when looking for hidden networks
