My ESP32 is running on batteries. I am using mDash 1.2.14-idf, IDF 3.3.5, with heap and stack debugging turned on. In case the router is down and WiFi is inaccessible, the following two things happen (there might be connected, therefore I put them into single topic):
- Although I have registered for the network lost event with
mDashRegisterEventHandler(MDASH_EVENT_NETWORK_CONNECTED, onConnectedNet, this);
mDashRegisterEventHandler(MDASH_EVENT_NETWORK_LOST, onDisconnected, this);,
my onDisconnected is never called. I see the following in the log:
2021-05-12 15:15:06 I mDash.c:119:dev_cb disconnected, ram 115068
I (396432) MDash: Connected to Network (printed by onConnectedNet)
-
After certain time (minutes), my software crashes with the message given below. It is reproducible, it is just matter of time. On the device side, in the meantime the software tries to send messages to mDash cloud via mDashNotify as the disconnected event never arrived. Any clue?
