InfluxDB crashing device after a restart

Device: Sonoff POW

Version: >1.10.0

Steps

1. Flash >1.10.0 with InfluxDB support enabled (not sure if it happens in < 1.10.0).
2. Set-up InfluxDB connection
3. Restart the device
4. InfluxDB crashes start-up, restarts the device for 5 times, then device stops working completely
5. I can't reset it to factory settings as it restarts before the 10sec.

Temporal fix
Erase eeprom and not enabling InfluxDB support.

I traced down the problem to:

#!arduino

if (!_idb_client.connect(getSetting("idbHost").c_str(), getSetting("idbPort", INFLUXDB_PORT).toInt())) {

Apparently the connect call is failing somewhere and throwing an exception. Should be a problem of ESPAsyncTCP.

Decoded Stacktrace

[xoseperez]

I'm going to check it. The device stopping to work completely after 5 crashes is the system check feature, It basically disables non-critical features trying to reach a stable configuration. The device is such state only enables WiFi AP mode, OTA and telnet. So you can connect to it's AP, telnet to it and disable InfluxDB, for instance.

The problem is with the initial heartbeat message (freeheap and uptime sent to InfluxDB). It was called from the mqtt on connect callback. Bad idea. I moved it to the main loop.

I've also updated the InfluxDB module and UI configuration to allow the user to disable it with a switch or build an image with predefined connection values.

The changes are in the dev branch. Will be released with next version.

Awesome! Already compiled and uploaded the code on dev branch and it works! Thanks a lot!
