ESP32 kills Asus Blue Cave Router

[samsonch]

When we connected ESP32 with an Asus Blue Cave router, it (this ESP32 connection) simply killed the entire router. Any connection sessions of the other devices with this Blue Cave died. We tried the standard example code came with the SDK, same result. Even the Blue Cave was set to AP mode, same problem. I called Asus Customer Care, they could not help at all. After the router was killed, the log showed:

May 13 21:49:06 kernel: [ 332.230000] [cbm] { cbm_queue_flush : 3647 }out QOCC 0

Any idea?

I have exactly the same issue. I have tried with esp32 from another brands but same result so yes, it's a router problem. Do you have stock firmware?

Hello Sergio,

The firmware version of the Asus Blue Cave was 3.0.0.4.384.45708. That is the officially released version by Asus. I tried to contact Asus support, but helpless.

Same to me, told me to reset router, set defaults... Nothing useful... and very frustrating... Another router works great

I purchased a asus blue cave router with firmware version is 3.0.0.4.384_32948

But I did not encounter the problem you described.

Can you guide me to reproduce the problem?

Hello,

I have the same issue. My problem is related to MYSA smart thermostat. As soon as I try to connect it to the router. It crashes the whole network. The network currently supports 23 IOT devices.

I can provide logs and so on.

My temporary solution is to use a range extender that connects to the blue cave that provides the internet connexion to the smart thermostat.

I think you need to find Asus official to solve this issue.
