OpenMQTT Gateway 1.6 MQTT ESP restart not working consistently

Theengs OpenMQTTGateway Bluetooth gateways
1

Hi,
I have been running OpenMQTTGateway on a couple of ESP32-WROOM-32U boards for a few weeks and I have been experiencing either a unresponsive WebUI with MQTT publishing still working or a complete hang after a few days. I have no practical way of capturing the logs so I thought I would just periodically restart the ESP32 via the MQTT command:

mosquitto_pub -t “home/OpenMQTTGateway/commands/MQTTtoSYS/config” -m ‘{“cmd”:“restart”}’

I can see the command being published but the majority of the time the ESP32 does not appear to respond to restart or status commands via MQTT . Should ESP32 acknowledge the restart or status commands directly?

Hello,

Yes you should see the uptime decreasing with the publication of a new SYStoMQTT message.
Which environment are you running?

3

I rarely see the uptime reset after the command

I have Home Assistant connected to the same MQTT broker but I’ve just been using CLI mosquitto commands and MQTT.fx to monitor traffic.

4

BLE, RTL_433, RF ? for example

5

I am running esp32dev-ble

6

I’ve noticed that both gateways are resetting after an uptime of less than 2000 typically. freemem = 93680 minfreemem = 31312, freestack = 3132

Here is part of the log file:

************* WELCOME TO OpenMQTTGateway **************
N: OpenMQTTGateway Version: v1.6.0

I logged it for a few hours and it crashes consistently right after scan 28.

@1technophile any thoughts?

Hello,

Could you try the new development version tomorrow (once the nightly build is done) and see if you get better stability?

10

Hi Florian,
I will try the new development version when I return from travel in a couple of weeks.

@1technophile I loaded v1.7.0 and it throws an exception after scan 28.

12

Did you erase the flash when uploading?

13

This was a new ESP32 module and the flash was erased.

14

Which BLE devices do you use it with ?

Could you try it with bleconnect at false ?

15

I have a (4) Xiaomi LYWSD03 flashed with pvvx.

I have tried to change bleconnect to false but I do not see the MQTT command changing the config value in the GUI.

mosquitto_pub -t home4/OpenMQTTGateway/commands/MQTTtoBT/config -m ‘{“bleconnect”:false}’

I don’t see a MQTT response after the MQTT command.

16

Try to add "save":true to the json payload.
Also do you reproduce the issue with different ESP32?

17

I have had the same exception after scan 28 on 3 different ESP32 modules.

I have bleconnect set to false.

18

It continued to run past scan 28

19

@1technophile It threw an exception at scan 198.

Could you share the version you are using and your parameters ?
