Question

Hi, We are using your WIZ107SR-TTL in one of our designs and we have relevantly large number of devices/modules which are not responding to you config tool or serial debug. Most of these devices were initaliy reponding but stoped working for unknown reason. Kidnly advice what can be done regards, Yaniv

Hi. Please, we need to detail information. What’s happens in module? When your WIZ107SR-TTL not worked, It was turn off LED? or Is the TCP connection lost? How made to whole your system? First, We want to know that why happens this action to WIZ107SR-TTL. So please tell me detail information. Thanks

Yaniv_Reibenbach: The probelms happens in diffrent scenarios: Stopped working after configure once or more Stopped working at customer’s site while no changes occuer and no body touch Firmware upgrade failure Few device never worked even once - from production they don’t work It is very difficult and complex to find the cause of these symptoms in many products. Are all of these phenomena found on one site? How many of the products did you find a problem with? Is the product installed in an environment that is susceptible to electrical damage or noise? Please check the followings: Is there a possibility that the serial debug message output will cause confusion to the device connected to the UART? Is there a possibility that the IP addresses of the devices connected to the same network are duplicated? Wireshark packet capture file at the time of the problem occurred - It can be checked on your server

Hi The modules are not responding to anything! not serial debug and are not found using the ConfigTool. The uart is not transmitting any signals. there is no ethernet data created and not visual viw wireshark
