I'm having a problem whereby my esp-01 modules lose connection after a while (10-40mins). No response, ping time out etc..
I'm using a lua firmware...
Access point is a tp-link ac750.
Strangely the esp-01 chips do not show up in the routers dhcp list..
If I hook-up to the chips uart, I can communicate fine with it and I can see the chip is still "running".
If I send the lua commands to disconnect from the ap then reconnect, it starts to talks to the wifi fine again and respond to pings etc...
It's like the wifi side of the chips is going to sleep?
Anyone have any ideas?
