Zephyr OS is same as nRF Connect SDK if I understood it correct. I posted the following question on the Zephyr OS mailing list. Am unsure where I might get an answer, so requesting help here.

So when this emulation starts in a setup with BabbleSim, the Linux host where this emulation is run should be able to access this UART. I could hook this UART under Linux&#39;s Bluetooth stack Bluez. The nrf52_simm with the HCI UART can be readily connected to Bluez stackwith a simple Linux command line. With this a Linux BLE apps should be able to participate in BabbleSim where other nrf52_sim with BLE apps (e.g. heart beat, temperature, beacon/advertizers, etc) are running. With this I might be able to test in simulation various complex combination of BLE devices which are harder to do with real RF environments.<br />If I see QEMU emulators (e..g. emulating ARM&#39;s MPS2_AN521), the UARTs can be exposed to the host running that QEMU instance. QEMU provides various options to expose this UART to the Linux host, e.g, over a PTS device. Does this help?Regards.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/462453?ContentTypeID=1Wed, 03 Jan 2024 10:26:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:06f4dc35-20e5-49bf-8e5e-24a14230354cSigurd<p>Hi!</p> [quote user=""]I would like to use Babblesim to connect a Zephyr BLE peripheral to a Linux app that uses Linux Bluetooth stack Bluez.[/quote] <p>Could you elaborate on this ? Is this a real peripheral device, that you want to connect to the Linux-machine(BLE Central) over BLE ?</p><div style="clear:both;"></div>
