Unimplemented commands


#1

Dear Anybody!

On latest firmware (1.0.3.3) I recognized the following problems:

If I try to set using AT+MEVTMSG= command then I got [ERROR: INVALID INPUT] response.
If I try to set using AT+MEVTFORM= command then I got [ERROR: INVALID INPUT] response.
If I try to set a region using AT+WREG=US (for example) then Wiz250 become reset (watchdog?) and I got “WizFi250 Version 1.0.3.3 (WIZnet Co.Ltd)” message.
If I try to set using AT+MWIFIPS=0 command then I got [ERROR: INVALID INPUT] response.

This commands are implemented?

There is some restriction where I can use this command. Today I use it after reset before I setup AP type and before I connect to it.

Thanks for any advise, kzsolt2

Hi, kzsolt2!

–> I am sorry that it is not implemented.

–> When the region is changed, WizFi250 become reset. And WizFi250 becomes a right region.

In case of station mode, you can use this command like below.

Dear Tom!

This mean if no AT+MWIFIPS command entered in station mode then power save is disabled?
Enabled only at first AT+MWIFIPS=2 command?

What is the recomneded sequence to change region?
Tipcal wizfi setup sequence is:
1). chip reset
2). set region (chip reset again)
3). set station mode, power save …
But contain double chip reset.

Moreover AP can send region information at connect to.
This can be enough or required to set region by AT+WREG?

Best Regards, kzsotl2

hi!:slight_smile: kzsolt2

–> Yes, disabled is default. It works AT+MWIFIPS =0, AT+MWIFIPS =1, AT+MWIFIPS =2 also.

–> 1) chip reset means chip Power on?
If then, I think it is right.

–> Yes, It is enough to set region by using AT+WREG.

Best Regards,
Tom

Blockquote 1) chip reset means chip Power on?

No.
For sure after power on I done a chip hardwer reset (contorlled by MCU) at step 1.
Power on is setp 0.

Hi, kzsolt2

Is there a reason to reset a chip at first?

If there is, your right.
Or not, After Power On, set region.
And then, set station mode and power save etc !:slight_smile:

Thanks,

Dear Tom!

Is there a reason to reset a chip at first?

My hardware specialst are inserted an LM809 MCU reset chip to monitor power good condition and then release hw reset.

Therefore this is some kind of “just for sure”.
I need a very stabile operation.

Anyway, the double reset need less than 1+1sec.
This can be good price for very stabile operation.
