Wifi problem: Esp doesn't get proper IP assigned #19

Closed jokober closed 3 years ago

jokober commented 3 years ago

Hello, first I want to thank you for your great work!

Unfortunately I am struggling to get everything to work. So far I only have the sd card module and the rfid reader connected. I had some issues to get the sd card reader to work with my Lolin32 Lite (no 5V pin) but managed to solve the issue by using a external 5V source to power the sd card module. This is not a nice solution but it works for the moment.

After connecting to the access point, changing the wifi settings and restarting the esp is not properly connected to the network. I can see the device in the fritz!box settings but it has no IP assigned. DHCP is aktivated.

The output also looks really weird:

Have you experienced similar problems or do you have any idea what might cause the problem?

Hi,

hmm, I've never been working with a Lolin32 lite. However, I've been told that this boards makes use of a weak voltage regulator. The user said he wasn't able to get the SD-card running until he used an external voltage-regulator. So (to be honest) just a rough guess: maybe a problem due to the regulator?

Have you already been using this board with a simple Wificlient-sketch or so? Just to make sure it's working in this case.

I am not using a Lolin32 Board but sometimes i am running in a similar issue. I have the presumption that MQTT might bring some problems when no broker is configured in your network. Maybe you can try to deactivate MQTT for a first try. Just deactivate the MQTT config in settings.h from #define MQTT_ENABLE
to //#define MQTT_ENABLE

@jokober Have you been testing my latest software-revision? Just asking because I revised MQTT-handling recently. Maybe your problem is resolved now.

jokober commented 3 years ago

Sounds promising. I will be able to test it tomorrow evening. Thanks for the help

jokober commented 3 years ago

Disabling MQTT as well as the new software-revision did not fix the problem. Unfortunately I don't have any new information which might help to solve the issue. I will let you know if I sind out more

jokober commented 3 years ago

I managed to solve the problem. It was kind of obvious but still took me some time. First I realised that I could connect to the network with a static IP.

Next I made sure to connect to the network by removing following line:

And voila it works!

Thanks you! Fixed it.
