CC2755R10: 6LowPan stack

Hi, Ryan

1.We now need to develop Matter 1.5 devices that use only BLE for IPv6 communication, requiring the IPv6 over BLE mode (BLE only, without Thread). Are there any relevant example codes available for the CC2755?

2.Does this mean the CC2755 is incapable of achieving IPv6 communication over BLE, or does it require us to develop it ourselves?

CC2755R10 only has a 2.4 GHz radio

3.If it is not possible, which chip series can achieve this functionality, and are there relevant example codes or documentation available?

Best regards

Thank you for the additional context.  Technically the Thread stack uses 6LoWPAN to act as an adaptation layer between the IPv6 networking layer and the 802.15.4 link layer.

1. Matter examples currently use Thread to communicate over IPv6, and BLE is reserved for commissioning.

2. The CC2755 is capable of achieving IPv6 communication using the IEEE 802.15.4 MAC/PHY, BLE is not considered a typical use case by TI and would required further development from your end.

3. Thread devices use 6LoWPAN to transmit IPv6 Packets over IEEE 802.15.4 networks.  You can review TI's Thread and Matter solutions which utilize IPv6 over Thread.

Hi, Ryan

Thank you for your response. Additionally, I would like to ask if you have any example code for IPv6 over BLE? If I want to integrate 6LoWPAN into the Bluetooth stack, how should I go about developing it? We hope to implement this functionality on the CC2745 or CC2755.

Best regards

Unfortunately TI does not offer any example code or instructions for IPv6/6LoWPAN over BLE as far as I'm aware.
