Re: Does the Esp32 support hardware based I2C or software bit-bang based I2C ?

There is a great post on the roadmap of the ESP32 that can be found here: http://esp32.com/viewtopic.php?f=10&t=375 What you will find is that the current drivers for the ESP-IDF framework are far from complete. The plan by Espressif is to try and make those available by the 1st of December which is...

Re: esp32 - sleep mode

I believe the answer lies in calling "system_deep_sleep()". This takes a parameter of the number of microseconds to sleep for. When called, the device will all but power itself down and when the interval duration has passed, it will wake up and start again. I believe some small amount of non volatil...

Re: WIFI_MODE_APSTA Sample

Howdy, What would you like to see as a sample? If you loosely thing of the ESP32 as having two distinct network interfaces ... one for connecting to an access point (the ESP32 being a station) and the other for being an access point, then you pretty much have it. What are you hoping to see in a samp...

Re: SPI Usage

The code for the drivers and much of the "environment" in which we will run ESP32 apps is still being baked. If we loosely think of needing an SDK to build apps properly, then the SDK we have right now is beta. See the following golden post for details: http://esp32.com/viewtopic.php?f=10&t=375 The ...

Re: new features?

Re: hidden ssid for WiFi.

When the ESP32 offers itself up as a WiFi access point using the api "esp_wifi_set_config" its parameter is an instance of a "wifi_config_t". This has a flag called "ssid_hidden" and if set to true, the ESP32 will not broadcast its SSID.

JavaScript on ESP32 - Duktape

Ive been tinkering with an implementation of a JavaScript interpreter called Duktape and it ported instantly to the ESP32. Very nice. Duktape can be found here: http://duktape.org/ Its been an interesting journey so far. I started with Espruino JavaScript and that took "moderate work" to get running...

Re: .Net Micro Framework on ESP32 chip

Maybe post some links and thoughts and what .Net micro framework is. I for one don't know and if there was a link, I'd click it. Also, what skills do you need assistance with? What do you foresee as the major tasks?

Can we determine information about open socket connections?

I recently found that I was running a broken app that ran out of sockets (max = 16). It would have helped me a lot if I could have "queried" the environment to obtain a list of TCP/UDP/Socket connections in use. Are there are APIs that I can use to "interrogate" the environment to find out what conn...
