We have been producing our products using WizFi210 firmware level 18.104.22.168 for some years. We recently received a shipment of WizFi210 comprising a mixture of firmware 22.214.171.124 and 126.96.36.199. Our products continue to function with
188.8.131.52 but fail with firmware 184.108.40.206. Our implementation uses multiple sockets with a mixture of UDP and TCP.
We determined that 220.127.116.11 does not return O or F in response to sending data using escape sequences.
Section 18.104.22.168 of WizFi210 Programmers Guide Version 1.3 omits response O and F when sending using escape sequences.
Section 22.214.171.124 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
Is this a simple error in documentation?
Or does 126.96.36.199 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 188.8.131.52 to return O and F in response to sending using escape sequences? Our product firmware is expecting these responses from WizFi210.
