WizFi210 Firmware 1.1.1.0 <Esc>O & <Esc>F


#1

We have been producing our products using WizFi210 firmware level 1.1.0.5 for some years. We recently received a shipment of WizFi210 comprising a mixture of firmware 1.1.0.5 and 1.1.1.0. Our products continue to function with
1.1.0.5 but fail with firmware 1.1.1.0. Our implementation uses multiple sockets with a mixture of UDP and TCP.

We determined that 1.1.1.0 does not return O or F in response to sending data using escape sequences.

Section 4.3.2.1 of WizFi210 Programmers Guide Version 1.3 omits response O and F when sending using escape sequences.

Section 4.3.2.2 of WizFi210 Programmers Guide Version 1.3 declares that response O and F is sent to serial
host when receiving using escape sequences. This is not logical and exactly the compliment of behaviour of firmware
revision 1.1.0.5.

Is this a simple error in documentation?

Or does 1.1.1.0 in fact not return O and F when sending using escape sequences?

It appears that this is the case.

Is there a configuration command that will cause 1.1.1.0 to return O and F in response to sending using escape sequences? Our product firmware is expecting these responses from WizFi210.

Yes, you’re right.
<1.1.0.5 f/w> returns O or F, but <1.1.1.0 f/w> doesn’t return them.

Please refer to the below link.

And, there is no way to enable O/F.
