Getting external flash to work - many questions!

Hi all, I'm having some trouble understanding some of the documentation on getting an external flash module to work on an ESP32-S3. I have a ton of questions! When the docs reference "external memory", is that referring to just off-chip memory? or off-module memory? I have an ESP32-S3-WROOM-1-N8. Is...

Re: [Answered] Maximum number of open sockets supported

Has there been any updates to this? In the HTTP web server, the maximum of 13 open sockets isn't enough when you're potentially dealing with both websockets and regular HTTP requests.

Maybe look into the RMT peripheral...
Good call! I tried using the RMT peripheral today and creating a custom tx encoder and it works well.

Just need to figure out rx decoding. :)

10-bit serial at 100 kHz

I have a device that has a very non-standard serial interface. It uses something like 10-bit serial at 100 kHz. On my logic analyzer, it looks like: https://i.imgur.com/Pz8QHFz.png Is it possible to configure the UART to read this data format? I'm currently trying to bitbang a solution, but I'm runn...

Multiple BLE connections

Is it possible to have multiple concurrent BLE connections on the ESP32? The documentations says it supports up to 9 client devices, but I can't even get two concurrent connections using the GATT security server example code (https://github.com/espressif/esp-idf/tree/master/examples/bluetooth/bluedr...

Re: esp32 AP DNS server sets a default route, it shouldn't, this breaks my phone

Sorry to bump an old thread, but I'm having trouble with this exact problem. I'm currently basing this off of the softAP example in the espidf repo. In my `wifi_event_handler`, I think I'm correctly unsetting the gateway and DNS, if (event_id == WIFI_EVENT_AP_START) { ESP_LOGI(TAG, "WIFI_EVENT_AP_ST...

Routing in soft AP mode using esp-idf

I'm pretty new at using an ESP32, so please bare with me. I have an ESP32 and I've been playing around with soft AP mode and connecting to my phone to it. I'd like to be able to connect to AP from my phone while simultaneously maintaining the cellular connection. I'm fairly sure this is somehow doab...
