I have already created another topic on this problem called Border Router OTA using WiFi, which was getting rather long and if I continue that thread, it might deviate from what I initially asked. So I wanted to raise a new topic to ask this question.
Since I do not have IPv6 on my WiFi network, I am currently attempting a workaround by making an ESP32 AP. I setup a Linux (Ethos) ā ESP32 (WiFi_AP) router using the same gnrc_border_router example, to which other ESP32 boards running the actual WiFi<->SLIP router from my original setup can be connected. I am not sure if this will work and Iād appreciate some suggestions.
I added a line in the Makefile.board.dep of the gnrc_border_router example to setup an Ethos<->WiFi router.
@@ +7,5
ifeq (,$(filter native,$(BOARD)))
ifeq (slip,$(UPLINK))
USEMODULE += slipdev_stdio
else ifeq (ethos,$(UPLINK))
USEMODULE += stdio_ethos
+USEMODULE += esp_wifi_ap
else ifeq (wifi,$(UPLINK))
ifneq (,$(filter esp32 esp8266,$(CPU)))
USEMODULE += esp_wifi
I can see the following ifconfig output on ESP32 (AP)

Using the suggested Makefile changes from the topic Border Router OTA using WiFi, I connected another ESP32 to the AP, setup the ESP32-Nucleo connection and got the same outputs as before.

I am able to ping the ESP32 router which is connected to the PC (Ethos<->WiFi). I need to know how to setup a route so that I can ping the Nucleo node from the Linux PC. The end goal is actually to trigger a SUIT update on the node, but initially I want to know if this is going to work.
