What settings (if any) might influence the time it takes for the AP to show in Windows or Android when they scan for networks? It can take a few seconds to appear even when the ESP32 has been powered for a while.

ESP IDF 3.3.

AFAIK you cannot power save whilst being able to receive on CAN without losing data, unless the ESP32 is the only device on the bus doing the ACK, then there should be retransmits. You can wake the ESP32 on CAN bus activity due to change in level on the Rx pin.

NVS as blob to avoid string limit. There is an Espressif tool to make NVS partition data.

It worked, but I did not continue using it. Doing an OTA update of all the code and data together was easier to use and support for our application. Run time scripts were small and fast by parsing them with std::string so did not have to bulk it with and learn Lua etc.

Dev boards from various sources might have firmware, but modules we had from Espressif directly do not and this is the standard AFAIK.

Thanks!

I use std::map, std::string, std::vector, find and iterators. The error messages are not nice and some things need just as much care for memory management as malloc/free because you can easily run out of PSRAM, it comes down to design and algorithm, and appropriate use and I would not criticise C++ ...

Anyone?

Is that loop ever going to be blocked/yield or just burn up CPU cycles?

I've been reading the documentation and include files on Bluetooth classic and looking at examples, but am new to Bluetooth and struggling. My desired use case is to get an ESP32 to become a Bluetooth source to be able to send track/artist strings/metadata to a bluetooth sink device that is a media ...
