Hi Ivan, Ok, understood the issue!
Maybe U-Block has an HCI H4 firmware that you can use on Anna-B112 instead of this AT firmware. It's always a good idea to use and follow the standard, this is a compelling motivation to use NuttX in the first place! :-) BR, Alan On 10/14/22, Embedded Systems <ivanucherdj...@gmail.com> wrote: > Hello Alan, > > Unfortunately we cannot use the module as HCI H4, we can control it only > with AT commands.
