@SOS . Sure will add that, actually I thought it did already work with both / & \ .
@HAL 6128 thanks for testing and feedback!
Looks like I'm the only with this issue for some reason. My card is one of the originals, is that part of the issue?
No, but came to think of it, it may have to do with the different batches of ESP12F's used. There may be modules with a different size flashchip, than 32Mbit, which I have assumed for the latest builds.
Will make a new test for you later today
Some routers don't like talking to the esp8266 (either because they don't support one of the minor protocols, or it sends a weird/large packet that confuses the 8266)
Previous updates worked for him fine.
In latest beta's I finally upgraded the ESP NONOS sdk & libs to v2.2.0 from v1.5.x, this seems to be causing the problem.
One difference is that with the old one I could simply erase the entire chip and put on my firmware without initializing the init data (@0x3FC000 for 32Mbit and here I need to make the other offsets if different size flash is used).
