  • @Gordon One crazy idea ... try to use ESP 12-F with 4 MB... the first 1MB to use for the FW of 8266 when the chip 8266 is ON (new AT FW is larger than 512 KB)... the remaining 3MB to use as extrenal flash for MCU when the chip 8266 is OFF ... or divide it 2MB/2MB for 8266/MCU... it is certainly possible in the case of own circuit design...
