AT+SYSMSG=0 does not disable WiFi connection related messages about esp-at HOT 3 OPEN

@BornaBiro Hello, you should use AT+SYSMSGFILTERCFG to set up system message filters and enable the filter by AT+SYSMSGFILTER=1. Here is a detailed example.

AT+SYSMSG usually used for Passthrough Mode, you can refer to the parameter explanation under the command for more details. In your case, AT works in Normal Transmission Mode.

That was exactly what I used as a workaround in the meantime and it worked perfectly.

One this that I noticed with AT+SYSMSGFILTERCFG is, if there is head and tail regex sent as described here for passthrough mode for removing tail and header form the HTTPCGET on every received data, after sending AT+SYSMSGFILTERCFG with it's parameters and waiting for ">", I must send separate SPI transactions for head and tail data, otherwise ESP32 just hangs.

So, if I need to enable filter for the HTTPCGET to remove header and tail from every HTTP data I need to:

1. Send AT+SYSMSGFILTERCFG=1,18,3\r\n
2. Wait for response OK\r\n\r\n>
3. Send ^+HTTPCGET:[0-9]*,
4. Wait at least 5 milliseconds
5. Send \r\n$

Is this is intended behavior? Because I did not see anywhere documented that head and tail data must be sent separately with some delay in between.

@BornaBiro This is not the expected behavior. Could you mind providing your log port logs?
i would like to reproduce it next week, maybe.
