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.
