Re: ESP32 and support to SNMP in LWIP?

We do not have plans for that. However, because ESP-IDF supports a fair amount of POSIX APIs, it's probably not too hard to port a C/C++-based SNMP library over to it.

Re: i2s parallel interface to monochrome lcd with 4bit data bus

Maybe something you overlooked: It's not the pixels that are swapped, it's the actual bytes getting loaded into the I2S path. So instead of just swapping the pixels around, you should swap around the way you write into the I2S buffer. If you don't, the sync signals will still be written 'straight' a...

Re: Mesh -demo on WROOM-32

The ESP8266 is, as the name implies, for the ESP8266; flashing it on the ESP32 is not going to work. We have a mesh solution for the ESP32 in the works, but at the moment that is not released yet.

Re: BLE Deep Sleep

Yes, this is what deep sleep does: power off everything but the RTC domain. Main memory also gets powered down, so the processor state is essentially discarded (the 'reset' you mention). At the moment we do not have a suspend method that allows the CPU to continue execution, sorry. What you can do i...

Re: ESP32 minimum operating frequency for Bluetooth operation

From memory, BT should work at 80MHz as the lower boundary; have you tried this?

Re: esp_task_wdt_feed() wdt feed error

Thanks for mentioning this. We are aware of this issue and it'll be fixed in a MR that overhauls the entire watchdog code slightly; should be coming into master shortly.

Re: i2s parallel interface to monochrome lcd with 4bit data bus

No, it doesn't: the I2S DMA engine will finish sending out the current buffer and when it gets to the last element, instead of restarting the chain it was on it will load the first descriptor of the new buffer and keep sending that out. No need to tweak the registers yourself. The maximum of 4096 st...
