ESP32C6 device disconnects by itself

[jrossouw]

Hello,

I have built a couple of Zigbee end devices based on the esp32c6 platform. Generally they work really well - although the range seems a bit limited.

I have recently started encountering an issue where some of the devices (of different types - one a tank level pressure sensor, the other a driveway alarm) seems to loose connectivity with the Zigbee network. They work ok for a while, but then sporadically seem to leave the network - and i have to rejoin them. I have noticed this especially on battery powered devices where the battery goes flat - and then when you recharge it the device boots up and indicates that it has not joined any Zigbee network. Could the flash become corrupt under low voltage conditions?

What other mechanism might result in the device disconnecting by itself?

Kind regqards,
Johan
