repeating timer limit

Does anyone know if there's a limit on the number of repeating timers (setup by os_timer_arm(..., 1)) which can be active at the same time? Just interested to know if it's more than 1 because my code appears to be blowing up now I've introduced a second & wasn't sure if that was the reason

Re: Calculating flash size

Yeah got that, but why are there two? e.g. does my flash image have a maximum size of 512 or 1024?

Calculating flash size

Could someone explain the flash size characteristics of the ESP8266. So, I can see when I flash that it is detected as an '8MBit flash', which is indicated as '512KB + 512KB' using the flash tool in info when you hover over. This is also alluded to in the 1.4 SDK by the "512+512" folder co...

Re: Meaning of ICACHE_FLASH_ATTR

That's disappointing, never mind.

Any rough ideas? I have no idea and I've been using it roughly at random. Something to do with the memory the function is compiled to / speed of calling?

Meaning of ICACHE_FLASH_ATTR

Could someone point me in the direction of where 'ICACHE_FLASH_ATTR' is described in the documentation please? I can't find it in either the SDK or HDK user guides.

Re: Specify DNS Server in SoftAP mode

This is exactly what I'm using. Unfortunately it doesn't seem to work. I can see the DNS requests arriving but the browser on my laptop doesn't get redirected to 192.168.4.1. Chrome displays a DNS_PROBE_FINISHED_NO_INTERNET error.

Re: Specify DNS Server in SoftAP mode

That's what I thought, thanks tve. The dns_setserver doesn't work either. Looking at the difference between the standard SDK binary release and my soft-ap hosting code, I can see that the binary SDK release is somehow specifying the DNS server, but I'm not sure how to replicate this in my code. In a...

Re: Specify DNS Server in SoftAP mode

But aren't these functions for station mode? i.e. to set the DNS server to use when the chip does a host lookup?

I'm interested in setting the DNS server for clients connecting through the wifi interface to the chip itself.

Maybe the function does both though, I'll have a go in any case.

Specify DNS Server in SoftAP mode

How is it possible to specify to those connecting over soft-ap mode what DNS servers to use? As with others here I'm trying to implement a captive portal and would like the DNS server to be the gateway IP. I can't see anything in the documentation but may have missed something. Is it possible? Thank...
