Re: Jump to first stage bootloader

You might be able to store a copy of the esptool loader in flash and copy it to ram and execute it. Or you could just do OTA over serial.

Re: Simultaneous WiFi and Bluetooth: Paket loss and WiFi disconnects

BT/wifi coexistence (Google it) probably has not been optimized for bt classic/a2dp yet. Even if it can be you may need a significant ram buffer to stream a2dp audio and use wifi with acceptable performance.

Problem on other platforms too https://github.com/raspberrypi/linux/issues/1402

Re: Can i create a ISR or interrupt and let that be pinned to a core?

Allocating an external interrupt will always allocate it on the core that does the allocation.

Re: Bluetooth support for ESP32 IDF 2.0 Release

No there will be more features in 3.1 but much easier to go from 3.0 to 3.1.

Re: Bluetooth support for ESP32 IDF 2.0 Release

I think it is too hard since bt and wifi are not all open source. And there are so many changes and fixes since 2.0, over 1800 commits.

Re: Can we run the ESP32 on 2x AA batteries

Gd25 3v flash only rated down to 2.7v? So yes it seems 2.3v is not relevant spec.
