Hi,

I'm trying to use rosserial with mbed microcontroler via ethernet/tcpip. I found that it work with arduino. Does it work with mbed platform?

Hi, It will be very useful for me to work. Could you please share the link of the source code

No, it is not supported on rosserial_mbed yet. I have added the support for the Arduino version but the mbed version only works on serial port. It could be added but I personally do not use mbed anymore.

Is arduino better than mbed? Why you choosed arduino?

Because at that time, mbed was only useful on NXP LPC series of microcontrollers and on STM32 you had to use direct registers to use advanced features. So I have use directly low-level programming on these platform. I know that now the support is better but did not try it yet.

And for quick tests, I use Arduino because I have some boards and I find it easier to use than mbed for simple tasks. Note that I have added rosserial ethernet support but I do not use it actually. It was because it was easy to add by modifying ESP8266 port.

What can I do for you, to have this feature?

Haha! I do not use mbed these days so I am not aware of the Ethernet interfaces. I am not sure if a common API is used across all Ethernet equipped mbed boards. Which platform do you use?

I use STM Nucleo STM32F429ZI. Ethernet works with https://os.mbed.com/docs/v5.9/referen...

Ok so it seems easy, you only have to provide a Hardware.h file with some methods implemented as here: https://github.com/ros-drivers/rosser...
