esp32-at won't build - loads of BT errors

[robf355]

Hi
I've installed the dev environment as per the website instructions, and loaded the esp32-at files.
when I enter make, after the compile I get:
LD build/esp-at.elf
C:/msys32/home/rob/esp/esp32-at/build/main\libmain.a(at_uart_task.o):(.literal.at_task_init+0x2c): undefined reference to `esp_bt_controller_mem_release'

plus loads more, a large number seme to be related to the ble, which I have disabled in make menuconfig.
I've done quit e alot of searches on the internet, buit nothing seems to work.
Am i doing something very silly?
Cheers
