Any chance of getting netcat working on Nuttx 8.2?

[greg5678]

So, it seems the Particle Photon's network functionality isn't working on the current version of Nuttx, but it does work on Nuttx 8.2. Is it possible to get netcat working on this older version of Nuttx on the photon? Just to see if it would work I took a copy of the current netcat folder from the nuttx-apps repo and put it in my /apps/netutils path. Then I selected it with make menuconfig and after running make -j3surprisingly it seems to compile successfully. The thing is after taking the nuttx.bin binary and flashing it to the Particle Photon it booted up and I was able to get a shell, but didn't see netcat. So, since that didn't work is there a way to get netcat running on Nuttx 8.2?

Hi @greg5678 unfortunately you cannot just copy a new directory from apps to old NuttX version neither vice-versa. You need to adapt the Makefile/Make.defs/Kconfig and even the source file C (in the past was name_main() now is just main() name), after that you will get:

$ telnet 192.168.0.16
Trying 192.168.0.16...

Kconfig: https://pastebin.com/raw/pU7urzR1 Make.defs: https://pastebin.com/raw/LTkeEmLq Makefile: https://pastebin.com/raw/JPNGPrTh Edite the netcat_main.c and rename the main function to netcat_main

Good luck!

Also, don't forget to run: "make apps_distclean" to remove previous configuration, after that run "make menuconfig" to confirm everything is configured!
