Hi,

I use growthbook to control features on my esp32s3. Growthbook uses SSE (server sent events) to send feature updates to my esp32s3 in "real time".
Is there already a SSE example, where the esp32 is the client and only listens to the server?

I tried to use the http_client library for that, but ...

Hi,

I have a project which is mainly written in C++ and uses a lot of new() . Somehow this causes the MQTT-client to not be able to allocate memory. I have tried to fix this problem by using different sdkconfig options, but I wasn't able to solve the problem. The free HEAP before the mqtt-client ...

Hi,

we are running in the same issue on esp32-s3 and idf 5.3.1, but with the mqtt client.
We have 5 Tasks of our own with total stack sizes 3kB to 6 kB (total stack size: 19kB). Then we use wifi and mqtt, so these esp-internal tasks are also running.
We also have a lot of const maps.

Before building the application image for OTA updating of an already encrypted device, enable the option Enable flash encryption on boot in project configuration menu.

For now my process is the following:


esptool.py --port $SERIAL_PORT erase_flash
espsecure.py generate_flash_encryption_key --keylen 512 ...

Hi,

does that mean, that after read-protecting all efuses it is impossible to read the MAC with esp_efuse_mac_get_default() ?
Is there any way to get the MAC? I mean WIFI need it to connect to a network or not? So there may be a way to get the mac-address after the WIFI hardware got it from the ...

Hi,

I was able to solve my issue by moving some stuff like .bss to the SPIRAM. I did also some changes in the menuconfig, I can post them in a few days, right now I am traveling.
But you don’t have SPIRAM, right? Well, maybe it will help somehow.

Hi,

could you solve the problem?
I get the same error when I am connected to my WLAN, which worked just 2 days ago and I did not change anything. Today it is not working anymore with my WLAN. But it works when I use a hotspot of my phone.

So the server-address seems to be correct and the problem ...
