Re: ESP32 VERIFY_PTR error gc_free CPU halted

Hi!
I have exactly the same problem as you described. Did you find a solution?
I believe it has to do with memory management.
A solution could be an autorestart of the CPU when this one gets halted. Any idea how to do this?

Re: ESP8266 does not connect to MQTT server anymore, ESP32 does, since new WiFi cablemodem is installed

I recently update my UnityMedia cable router to a Vodafone one (which apparently is an Arris TG3442DE). The WiFi authentication modes on this router are OFF/WPA2/WPA+WPA2. I tried all of them and it only works with OFF. The problem is reported at Vodafone since 2018, without solution. 'Rumours' say ...

Re: ESP8266 does not connect to MQTT server anymore, ESP32 does, since new WiFi cablemodem is installed

Hi Kevin, Thanks for your comment. I did not have problems before neither !! I believe the problem is the type of WPA/WPA2 which is used by the router. One is 'the classic one', which works ok (also for me, before I got my new modem with WiFi router). The other one is the enterprise one, which I bel...

Re: ESP8266 does not connect to MQTT server anymore, ESP32 does, since new WiFi cablemodem is installed

Apparently, the ESP8266 cannot handle WPA and WPA2 authentication properly! Both the ESP and router report that the WiFi link is up but nevertheless, no packets can be sent across. the ESP reports as WiFi status : - connected - authentication mode : 4 (same as configured at the router) When switchin...

Re: ESP8266 does not connect to MQTT server anymore, ESP32 does, since new WiFi cablemodem is installed

How can I trace what's going wrong at socket level during socket.connect? Is there any possibility to trace the TCP/IP activity for ESP8266 outgoing messages? I try to setup a mqtt connection and the 'connect' in simple.py fails due to 'ECONNABORTED'. The WiFi is connected (sta_if.isconnected return...

Re: ESP8266 does not connect to MQTT server anymore, ESP32 does, since new WiFi cablemodem is installed

I have setup the build environment and built a new version and erased and reloaded already several times, also with different versions, including the 'official ones'. Same result. II can see the MAC address and this is OK. Will look further for the software modules that are pulled in and keep you po...

Re: ESP8266 does not connect to MQTT server anymore, ESP32 does, since new WiFi cablemodem is installed

Hi TVE, I believe your remark about my faulty analysis is correct :oops: I cannot find a corrupted mac address in the Wireshark log. (Most likely, the router log displays it wrongly). The main issue is still valid: multiple incoming ARP requests from the ESP8266 till a maximum number of retransmissi...

Re: ESP8266 does not connect to MQTT server anymore, ESP32 does, since new WiFi cablemodem is installed

Thanks for your comment! The problem seems to be the router, who gets in the ARP response from the MQTT machine, the IP & MAC address of the MQTT machine and currupts the MAC address. I opened a ticket at my ISP provider to mention the issue. The Wireshark log at the MQTT machine, shows that the ARP...

Re: ESP8266 does not connect to MQTT server anymore, ESP32 does, since new WiFi cablemodem is installed

can anyone tell me whether the ESP 8266 IP stack uses the mac address or the IP address to send out IP packets? In my case since I installed the new modem, I observed that the MAC address of the destination module is corrupted by the new modem (last 3 groups are put at '0' - eg. 3c:7f:cb:00:00:00). ...
