SPWF04S File print issue

Hi!

I am using the SPWF04S module configured in MiniAP mode. I've created a file in RAM memory using the AT+S.FSC command.

I am reading the file using the AT+S.FSP command. After about 450-500 successfully readings, the module responds with Low Memory and resets itself (watchdog) after 20 seconds. Sometimes the respond is 'WIND:8:Hard Fault:ConUart:0002b290:20030000:07fd5003:08023588:47938cc4:fb3f49b6:080bb3e0:21000000' instead of Low Memory.

The same happens if I am creating the file using POST messages to the module. In this case I have the following steps:

1. I send this from client PC: curl -i -X POST -H 'Content-type: multipart/form-data' -F 'data=@FileSetX' 172.10.20.1

2. I read the module using 'AT+S.FSP=FileSetX,,'. The content of the file are read correctly.

3. Repeat 1 and 2. After about 400-500 success, the module is blocked (Low Memory / Hard Fault or maybe something else...)

Thanks.

Hi,

please attach here content of AT+S.GCFG command. RAM disk is static, so, cannot use more than that amount of RAM...

Thanks for 500 tests

Ciao

Hi!

Probably I was not clear enough. In the first case, I am sending AT+S.FSC command to create a file only ONCE. After that I am reading that file every second. After about 500 readings the issue appear. This should not be a RAM size problem, I am just reading a file containing 5 characters... This is a real situation, reading a file how many time you want should not be limited.

My purpose with 500 tests was to test my application not the module, but I found this issue on the module.

Here follows the AT+S.GCFG:
