Nov 7, 2022, 05:31 by hello(a)robcraig.com: Hi all, Seems the kernel panics when it receives certain characters in the chat app or telnet session chat that is does not like. This is then propagated (via Lora) to other Disaster Radios nodes and crashing them too. You can bring down the entire system this way. Not good :( When you clean the bad characters from the chat log on the SD card the system works again. But this means you need to get to each disaster radio node and clear the logs. This is the log on the SD card that seems to cause the crash: {"":4,"":"\u0000\u0000\u0000\u0000\u0000\u0000","":99,"":15,"":4,"":"\u0000\u0000ˆÛ9","":99,"":"\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000","":14,"d":"ˇˇˇˇc0","t":99,"m":"00c|~ android joined the channel\r\n","l":34} {"":4,"":"\u0000\u0000\u0000\u0000\u0000\u0000","":99,"":15,"":4,"":"\u0000\u0000ˆÛ9","":99,"":"\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000","":14,"d":"ˇˇˇˇc0","t":99,"m":"00c|<android>hi\r\n","l":17} {"?
