SDK 1.5.2 and liblwip_536

SDK 1.5.2 is missing liblwip_536.a, can you please provide it? It's pretty critical in memory constrained firmwares that need to support many connections. Thank you!
(Is there a reason you're leaving out of every SDK version?)

Re: avoid clock-out on gpio0 at reset?

You said GPIO0 will be connected to the programmer via a cable. Please let us know how you control the level of GPIO0 and how the 26Mhz clock cause noise issues. Please try the following experiment: take two esp8266 modules and try to program one of them using the other. Let's call "esp-A"...

is sntp one-time or periodic?

Can you explain what sntp_init() does? In particular, is it a one-time clock synchronization or does it contact the provided SNTP server periodically? If the latter, what is the period?

Re: ESP-NOW uses ACKs?!?

Given that the data rate seems to reduce I would assume that the ACKs and retransmissions are at the MAC (Wifi) layer, and not at the protocol layer. All 802.11 packets other than beacons pretty much have an ACK and I would not expect the ESP-NOW packets to be any different. Apologies if I'm telling...
