AT Command or Peripheral Shell Support for BL54L10/BL54L15

[Arunjyothi]

Hi,

I am planning to replace our existing CC2650 setup with the BL54L10/BL54L15 series. In our current architecture, an MSP432 microcontroller communicates with the CC2650 over UART using SNP protocol

Before moving forward, I need to confirm whether the BL54L10/BL54L15 firmware supports:

• AT Command Interface.

• or the Peripheral/Shell Commands for controlling the BLE stack and radio features over UART

Specifically:

1. Is there an official Nordic firmware image for BL54L10/BL54L15 that includes an AT command set?

2. If not, is there support for a peripheral shell (CLI) over UART that can achieve similar control?

3. Are there examples, documentation, or SDK packages that demonstrate this capability?

4. If custom implementation is required, what Nordic SDK (version) and modules would be recommended?

5. If AT commands or a peripheral shell are supported, what commands are available, and is there a complete command reference or documentation?

Hello,

I can find there are third party module manufacturers that have made AT command modules based on various nRF variants:
https://www.nordicsemi.com/Resources/Nordic-Partners/Third-party-modules 

I can't find anyone in specific mention the nRF54L series yet, so I guess you can reach out to a few of them to check if they plan supporting also the nRF54L.

I am not aware of any ready made example in our nRF Connect SDK that provide an AT command interface (other than for cellular, but that is not what you are asking about). So in this case you may need to write the application firmware yourself, where you write an application that expose a set of commands that allow you to control a bluetooth link as you best see fit. If you for instance start with the peripheral uart over bluetooth example that might be a good starting point, currently that simply expose a serial uart interface, but you should be able to add commands on top of it that control the link:

Alternatively there is a bluetooth shell example that might be a starting point also:

Here is a new open source AT command interface which runs on most Ezurio modules (BL54L15/L15u/L10, BL654/653/652, BL5340): github.com/.../ZAPHOD
