[Bug]: Wi-Fi Connectivity Loss on T-Beam v1.2 (Potential Memory Leak)

Hardware

T-Beam

Firmware Version

2.5.13.1a06f88

Description

Observed Behavior:

My T-Beam v1.2 loses Wi-Fi connectivity after 30~90 minutes and requires a reset to reconnect.

Additional Information:

I suspect a memory leak in the firmware as the issue seems related to memory exhaustion.

Attached are memory usage stats collected from the /json/report API during Wi-Fi operation.

I'm willing to help debug this issue and would appreciate instructions on how to proceed.

Same here with 2 t-beam supreme. Connection gets lost after some time, you have to reset the device.

It seems this issue is related to MQTT. When MQTT is disabled, the T-Beam remains connected to Wi-Fi and responsive for days without requiring a reset.
