I have an espnow application running satisfactorily, to which I am now adding bluedroid - spp. In order to minimise IRAM usage, I have disabled both CONFIG_ESP32_WIFI_IRAM_OPT and CONFIG_ESP32_WIFI_RX_IRAM_OPT. All of my queues use heap allocated in psram. The psram spi clock is set at 80MHz and the interface is DIO. This configuration worked well with the espnow application.

My first problem: I would like to change the psram chip interface to QIO. I cannot manage to find a combination of config settings that work for this. I have tried both the HSPI and VSPI hosts. Can anyone advise me on the best approach to solving this?

I get the following error:

In sdconfig, I note that there seems to be a conflict generated by menuconfig. I have CONFIG_ESPTOOLPY_FLASHMODE_QIO=y as well as CONFIG_ESPTOOLPY_FLASHMODE="dio" - see the listing below:

My second problem: When I add my trial bluetooth code, I get the following run-time error:

Any advice on solving these issues would be much appreciated
