2v06 ESP32 Static IP not available?

I'm running 2v06 esp32 espruino.

If I read the docs correctly (no options in connect and setIP is unknown) it is not possible at this time to set a static IP (although it seems possible for esp8266)?

Yes, just checked setIP, getIP() setAPIP() and getAPIP() are not jet implemented for ESP32 implementation.

If you like do the implementation.

Well if it involves CPP code that's a maybe. I've been exploring espruino as an option to writing CPP since CPP is not a language I know very well like node. Still, if it has been done for esp8266 maybe the implementation can more or less be copied.

ESP32 stuff is written in C.

Starting point is jswrap_esp32_network.c and jswrap_esp32_network.h

if it has been done for esp8266 maybe the implementation can more or less be copied.

Not sure about this, because ESP32 is a bit different.

This library from espressif has a config method that accepts static ip as demonstrated in tutorial below.

https://github.com/espressif/arduino-esp32/blob/37a7fb3d6ada8a9230c96e2df999c95ef10fd4d3/libraries/WiFi/src/WiFiSTA.h#L43

Can this just be incorporated?

Alternatively If I can't get to this I'll set up a fixed IP from my DHCP server based on MAC for now.

I guess this is what you are looking for:

// info about the structure 
typedef struct {
    ip4_addr_t ip;
    ip4_addr_t netmask;
    ip4_addr_t gw;
} tcpip_adapter_ip_info_t;


// STA calls
tcpip_adapter_dhcpc_stop(WIFI_IF_STA);
tcpip_adapter_set_ip_info(WIFI_IF_STA, const tcpip_adapter_ip_info_t *ip_info)

// AP - calls
tcpip_adapter_dhcpc_stop(WIFI_IF_AP);
tcpip_adapter_set_ip_info(WIFI_IF_AP, const tcpip_adapter_ip_info_t *ip_info)
tcpip_adapter_dhcpc_start(WIFI_IF_AP);
