WPA2 Enterprise EAP-TTLS Authentication Type Support

As of currently it looks like the WPA2 Enterprise EAP-TTLS method only supports MS-CHAPv2 Authentication. Is there any plan to add support for other Authentication types like PAP, CHAP, etc?

Thanks,

Re: esp_http_client post failing to timeout in bad Wi-Fi

I have tried using the esp_http_client_fetch_headers fix that was implemented in esp-idf 4.0rc and it reduced the issue slightly but is still occurring. my understanding is that the timeout currently is set up to be the timeout for each small action of the larger transaction, rather than being the t...

esp_http_client post failing to timeout in bad Wi-Fi

I am running into issues sending a post over a bad wireless network (network simply too far away for reliable transmission) where it sometimes gets stuck sending data to the server and does not timeout after 5 seconds as it has been setup in esp_http_client_init. This test is currently running on es...

ESP32 Modulation Data Rates

Hi, I have been looking through some of the datasheets of the ESP32 particularly at the WiFi modulation rates and initially I found that most datasheets only claim data rates of 6 and 54 Mbps on 11g like shown below: esp-wroom-32 data rates.PNG But recently I found the FAQ docs for ESP32 ( https://w...

ESP32 OFDM Rates

After looking at the ESP32 Datasheet it looks like the ESP32 is only capable of OFDM rates 6 Mbps and 54 Mbps. Is there any reason why it cant handle any of the intermediary rates like 18, 24, 36?

3.1 esp_http_client inserting headers into POST data.

Hi, I am using esp_http_client to send large chunks of data. We are having an issue where, very infrequently, the HTTP headers, set for the POST via esp_http_client_set_header, are being injected into the middle of the POST data. The data is a chunk of an image being sent as a 12800 length null term...

Re: Secure Bootloader Error despite being disabled

I found the issue. I had a preprocessor definition I was adding to CFLAGS with '=' instead of '+='. Over the past few days I have been slowly fixing issues that cropped up by adding more of those commonly used flags (-mlongcalls -ffunction-sections -fstrict-volatile-bitfields) when it was the '=' al...

Yes, I've had to use -mlongcalls due to issues in setting up our project repository.

Re: Secure Bootloader Error despite being disabled

As a temporary solution I have just changed the signature verification key initialization to be based off of CONFIG_SECURE_BOOT_ENABLED in secure_boot_signatures.c: #ifdef CONFIG_SECURE_BOOT_ENABLED extern const uint8_t signature_verification_key_start[] asm("_binary_signature_verification_key_bin_s...

Thanks so much!! I added the IRAM_ATTR to portENTER_CRITICAL_NESTED definition and it went off without a hitch.
