Hi, what is the preferred way to realize a datetime clock on ESP32? I'd like to get a reference time from the internet (e.g. via NTP) and set a local clock. The only thing I have found is xTaskGetTickCount(). Using this I can imagine something like uint32_t offset; void init_timestamp() { // get cur...

Be careful! Without encryption you are going to send your WiFi password in plain text over the air!

It looks like the mdns library does not add a PTR to your service to _services._dns-sd._udp.local

Looks like a bug!

Hi,

I am trying to implement HTTP Public Key Pinning (HPKP) using mbedTLS. The TLS connection is set up, handshake is done and I have the peer's x509 certificate as an mbedtls_x509_crt struct. Now I am stuck. How do I access the subjectPublicKeyInfo that I need to hash?

Thank you!

Best,
Malte

are you working on an http2 server?
that would be very interesting for me, too!

Best,
Malte

Great! Thanks for your assessment!

I will give it a try.

Best,

Hey,

I am wondering, is it possible to use an esp32's GPIO pin as a clock source for an external IC?
The IC needs a 4 MHz square signal. Can I use an esp32 hardware timer and do something like PWM for generating this clock signal?
What is the maximum frequency that can be realized?

Thank you!

Malte
