Hi,

is it possible to run an I2C master and slave on the same pins?
Additionally to the esp32 I have multiple I2C slave sensors on my bus and I have another microcontroller on the bus. The other microcontroller should act as a master and write to the slave esp32. But the esp32 should be able to ...

I have updated to the latest esp-idf SDK.
The problem disappeared.

Thanks.

Hi,

I wonder if there is a documentation about WiFi log output.
I get a lot of these messages and don't know what they mean:


I (699881) wifi: n:11 2, o:11 0, ap:255 255, sta:11 2, prof:1
I (700081) wifi: n:11 0, o:11 2, ap:255 255, sta:11 0, prof:1
I (700181) wifi: n:11 2, o:11 0, ap:255 255 ...

the connect() call takes quite a time.
Before it returns an error I get this line in the log:

I (16465) wifi: pm start, type:0

so it looks like this:


I (7304) HTTP: created socket with socket_id = 0x2
I (7405) HTTP: socket_id = 0x2
I (7405) HTTP: connect()...
I (16465) wifi: pm start, type:0 ...

Hi,

I have problems connecting to a remote server.
In one project my code works flawlessly, in the other the connect() call brings an ECONNABORTED error.
What can be the reason for a ECONNABORTED?

Thank you!

Somewhere was mentioned that a 3,3V power supply with 500mA is recommended when using WiFi.

Hi,

are the NVS access functions for writing and reading thread safe or do I have to use a mutex in my user code when accessing/committing the flash to prevent concurrent access?

Thank you!

Finally someone makes a secure IoT protocol, and its all locked away behind NDAs sad. Or at least I guess that this is the reason for not making that discussion public?

Great!

I have created a pull request to fix this issue:
https://github.com/espressif/esp-idf/pull/500

Best,
Malte

also the new lines in the request must be \r\n instead of \n

like this:

static const char *REQUEST = "GET " WEB_URL " HTTP/1.0\r\n"
"Host: "WEB_SERVER"\r\n"
"User-Agent: esp-idf/1.0 esp32\r\n"
"\r\n";


If this doesn't help, can you paste your whole C file in a pastebin or gist? https://gist ...
