For my HID device I need bigger than 512 bytes report map, currently I have to change this line

esp-nimble-cpp/src/NimBLEAttValue.h

Line 30 in cd115f1

# define BLE_ATT_ATTR_MAX_LEN 512

and in nimble as well
https://github.com/apache/mynewt-nimble/blob/baf2930d32c21222b77086181d842301bff9721f/nimble/host/include/host/ble_att.h#L227

Without changing this lines I get "driver error" in Windows, because my report map is not being sent.

If there is a way to send bigger than 512 bytes report map, please advice.

Thank you.

That would go against the BLE core specification.
