Is there a limit to the length of the data that can be submitted to esp_ble_gatts_send_indicate()?
Do I have to ensure that the data fit into a single packet, or will the GATT server break longer messages not small link-layer packets for me automatically?

Bluetooth library source code?
I've been running into some issues with BLE where packets arrive garbled very frequently and I was trying to look into the Bluetooth stack used in the ESP32. However, I can only find libbt.a as a library and no source code for it. Can someone please point me towards the source code for the Bluetooth...

Virtual address mapping through MMU
Is it possible to allocate some internal RAM and then tell the MMU, I want to access this block through the address 0xA000_0000, for example? The internal memory is too fragmented for me to allocate a large buffer I need, so I was hoping I might create a fantasy address space and tell the MMU to map...

-mmac16 compiler option not working in g++
Am I mistaken or does the -mmac16 compiler option to generate mac16 instructions not work using g++?

Code Performance Analyzer
I am in the process of writing some finely tuned modules where performance is critical and I was wondering if anyone is aware of any Performance Analyzers for the ESP32. I'm looking for something like VTune that will analyze my code—either statically or at runtime—and gives me information about cach...

Xtensa TIE Extension
I've been trying to see if there is a way to use Xtensa TIE Extensions with the ESP32 but it appears there is only the SDK available from Cadence for $1000/year per seat. Considering that virtually everyone tells me the SDK and tool suite is absolute crap, using an outdated compiler, broken tools th...

How to increase SPIRAM speed?
I am running an ESP32 with embedded 16MB SOM SPI RAM in quad IO mode at 80MHz. However, the RAM is rated at 133 MHz and I have not found a way to actually run the SPI bus for SPIRAM/PSRAM at any frequency other than 40MHz or 80MHz. Could anyone point me in the right direction how to go about doing t...
