Can ESplorer retrieve this ? --YES
I did find node.flashid() = 1458400 now according to docs SB number : id hex = 1640E0
2^16 = 65636 ???? 40 mhz E0 manufacturer
hmmmm! how to decode this? ESP-12E [Q]
nodeMCU DEV 0.9.6 20150704
My ESP-13 shows same 1458400
My ESP-201 shows 1261768 == 1340C8 hex 2^13= 8192 ??? 40mhz C8 manufacturer
flash size may be 2^xx-1 2^12=4096 000 / 8 = 512KB advertized ESP-201 flash
2^15=32760 000 / 8 = 4096 kb 4MB
Have not found manufacturer index
Suspect the 40 mhz is correct
