Looks good, no problems up to now. I've been building with SPIMEM_AGGRESSIVE before using the 3.1 defaults. With the two new bluetooth memory options enabled… CONFIG_BT_ALLOCATION_FROM_SPIRAM_FIRST=y CONFIG_BT_BLE_DYNAMIC_ENV_MEMORY=y …I now get this bluetooth memory footprint: OVMS# power bluetooth status Power for bluetooth is off OVMS# module memory Free 8-bit 66336/230084, 32-bit 232/376, SPIRAM 4045440/4194252 OVMS# power bluetooth on Power mode of bluetooth is now on I (140846) bluetooth: Powering bluetooth on...

Btw, I needed to change the signature of the xt_error_handler_callback to build with bluetooth enabled on the current esp-idf. I'll push that change to our esp-idf.

I’m doing some work on optimising RAM usage in OVMS v3.1. This is to try to make space for bluetooth, etc.
First step is fixing the (broken) SPIMEM_AGGRESSIVE option to work better. Saving is worthwhile:
Without aggressive: Free 8-bit 113116/281672, 32-bit 8020/24276, SPIRAM 4140964/4194252
With aggressive: Free 8-bit 137380/281640, 32-bit 8020/24276, SPIRAM 4108616/4194252
That is the first step only. We are still using far too much internal RAM, and almost the whole 4MB of external RAM is sitting idle.
The reason for this eMail: Hopefully I didn’t break anything. If I did, let me know.
Regards, Mark.
