Dear Nordic,
i have started my application with toolchain & sdk both v3.3.0, using custom services & charachteristics, with BLE advertising @500ms interval works fine. but when i disabled VCOM0 from board configurator and then in overlay declaring uart30 pinsP0.0 as TX and P0.1 as RX . Transmit works fine, But recieve not, even in polling mode. when i downgrade sdk and tool chain both to 2.8.0 it started works with all other functionality.
is it issue with sdk and toolchain 3.3.0 &3.31 , or any other method to get it work.
below is prj.conf
