Hi @Vasily. I have managed to flash a Sonoff device successfully. I have 3 devices and have managed to successfully connect one of the devices (unflashed) to my wifi. The Espruino flashed device (1v96) works great (can load and execute code on it no problem), but will not connect to wifi. I have an Espruino wifi device that I use the same code for and it connects fine. Funny thing is, with the sonoff device when I try to connect i reports no_ap_found (and list command to find ap's reports an empty array), but if I use an incorrect password, it reports bad password! That tells me it's finding the ap and reporting an incorrect password right? SO how come with the correct password it reports no_ap_found? any suggestions?
