Re: GPIO interrupts lost (hardware race condition)

First, I have managed to fix the problem. Thanks for your suggestions. My original code used the basic gpio_install_isr_service / gpio_isr_handler_add combo. IRQs were set up in loop like gpio_set_direction(GPIO_Pin, GPIO_MODE_INPUT); gpio_set_intr_type(GPIO_Pin, GPIO_PIN_INTR_POSEDGE); gpio_isr_han...

Re: GPIO interrupts lost (hardware race condition)

I've checked the master, but there was no related changes for this function, it was just optimized. It's a bit tricky to compensate for hardware bug in software, but I'll probably do that by comparing actual GPIO state before and after clearing the IRQ and rising an IRQ bit on difference. For your s...

GPIO interrupts lost (hardware race condition)

Hi all, I've found some serios problem with the GPIO interrupts. My hardware is generating 3 independent IRQs (about 200 per second each) on GPIO 34,36 & 39, configured as rising edge. Quite rarely (in a couple of hours or so) one of the IRQ signals is not getting latched in the GPIO IRQ status regi...

Enterprise authentication for mesh root not supported yet

Hi, It looks like there is no support for the enterprise (e.g. PEAP-MSCHAP) authentication for the mesh root WiFi connection, right? Any plans on implementing it? So far I'm using quite an ugly workaround pre-connecting the root and then providing incorrect router setup to the mesh, that's not reall...

Re: WPA2 Enterprise connection

PaulFreund, I am having exactly the same issue you've faced. Unfortunately, I don't have a lot of experience with enterprise WPA2 as well. Have you found any solution so far? Network I'm trying to connect to has been set up (not by me) with the following how-to: https://www.cisco.com/c/en/us/support...

Re: Mesh size limits

Thanks for the reply, very helpful. Two things to clarify: You have mentioned packet loss possibility, does this mean not the actual data loss but the increased delay due to retransmissions? And could you please estimate a practical limit and its parameters considering your knowledge of memory usage...

Mesh size limits

Is there any theoretical limit for a number of nodes? So far I've found limits of 10 connections to AP, 15 layers max total, and an uint_16t number of nodes. Does that mean that a number of nodes in a single mesh could reach 64K?

Thanks,

ESP-MESH source on Github

Will the source code for the ESP-MESH lib be ever available on Github? Not the ESP-MDF, it's already there. It is essential to have an access to it for production-grade use.

Thanks,
