Hi Björn,

Thank you for the explanation. I will decide what to do. In my opinion serializing is much better.

HI Halilb,

I am afraid that we do not have much experience with interfacing ethernet modules with the nRF52840, but ifs a serial interface then it should be fairly straight forward. AS for IPv6 support, you'll a have to look at the individual specs of the different modules out there.

Yes, I guess using a STM32F407/417 should be possible. You would then have to identify where in the IPSP layer you can extract the IP packet and transmit it serially to the STM32F407/417.

Hi Bjorn,

Yes, This what I intend to do. However, whether there is IPv6 support of ethernet module is another question that makes me confused. Another solution I think is using Stm32f4 with ethernet provided and nRF52 will only deal with BLE connections and data between nRF and Stm32 will be transferred over UART. Actually, since I am not experienced, I can not estimate the results of my ideas. Sorry, if I ask dummy questions. Thank you for spending time for me.

Best regards

Halilb

Hi Halil,

[quote user=""]However, now, I would like to replace RPi with nRF52. nRF52 will behave as BLE Central and 6LoWPAN router and an internet connection to nRF will be provided by ethernet. [/quote]

So you have a Ethernet module or similar that you have interfaced with the nRF52 acting as a central?

Best regards

Bjørn
