wiki section for elementary tips: how to get esp stable?

[tozett]

give some elementary tips for newbies (like me) to improve stability of esp-modules...

Good idea.

Another tipp is to use an RC-grid for the connection of CH_PD. A 4.7k resistor and 0,1uF. I have done that and its much more stable now and can better start.
Thats my mileage for this week with such a setup.

Uptime: 5600 minutes

(with Build 48).

anybody build a simple hardware watchdog to restart an ESP with poweroff/on?
it could hang also after 5600 min..

for having "reliable" ESP-nodes at some unusual places in home automation i would be good to
have an external/internal watchdog to reliably cold-restart the ESP. Anybody doing this?

i read here:

I send an MQTT "heartbeat" message to the boards from a central "controller" which is a battery backed-up Raspberry Pi2 - the ESPs have a flashing light on them that alternates every second. If that heartbeat does not arrive, I stop the flashing lights, try again to get the message and if that fails, reboot the board.

which seems a good idea for an _internal_ watchdog. maybe a wishlist feature?

maybe (right) handling of the ESP pins belongs to this thread, too.

if anybody looks here help with for spurios reeboots,
a hardware solution from costo can be read here:

i found this from 10/2015

Because of ESP instability, i have no short term plans to migrate Nodo controllers to ESP if it's an output device or if it needs rock solid uptime[/color]

so. we have to state here, if the development has brought a dramatic change to something better in stability

if ever anybody skilled comes here, looking for ideas for an hardware watchdog, external to the ESP,
may one uses a classical IC?
