For those that are interested, please see this pending merge request: #687. Testers and feedback would be appreciated. This upgrade to SDK 1.4 will resolves a lot of pending SDK related issues with the firmware. The available RAM is also significant;y increased. One limitation is that the firmware is extremely tight for fitting into 512Mb Flash modules, so those with ESP-1 class modules who want to use this will need to do custom builds.

try this
Code: Select allwifi.sta.config(SSID,PASSWORD)
print("wifi is loading")
print("please wait.")
print("please wait..")
print("loading" ..=wifi.sta.getip().." wifi info sent")


Then you can see if you are getting your IP or not... I had trouble trying to print it immediately after station it would just say 192. or 192.garbadgehere Its like you need a delay before you can print.

If this is what you are trying to do that is maybe I misunderstand a bit if I do just disregaurd this posting.
