WizFi210 Firmware 1.1.1.0 O & F

Question

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. [url]http://wiznet.co.kr/Sub_Modules/en/product/product_detail.asp?Refid=730&page=1&cate1=&cate2=&cate3=&pid=1132&cType=2[/url] And, there is no way to enable O/F.
