AP Cisco not getting ARP reply from ESP8266
Posted: Tue Mar 28, 2023 8:22 pm
We have Esp8266 implemented in our products, a customer of ours reported difficulties when connecting in WPA TKIP mode, he uses a Cisco 1242 router. When changing to TKPIP + CCMP the communication works.
We work with static IP, we notice that the module is associated with the router, it receives the ARP request, the module responds to the request, but we cannot see the response.
When running wifi sniffer we see the ARP response, but the router does not understand that packet as valid data.
SDK version: 3.0.5
