How to properly disable Bluetooth ?

Hi, I have an application that will mount a GATT server for a specific task. Once this task is done I need to be sure that the bluetooth is totally and properly disabled. Here is how it is initialized (note that I am using esp-idf v3.1.3) : static bool initialize_ble(void) { esp_err_t status = esp_b...

Re: Power management fail after WiFi join

It seems that one of the listen_interval field of a wifi_sta_config_t structure in my code was not initialized. This field is used when in WIFI_PS_MAX_MODEM mode.

Re: Power management fail after WiFi join

For a moment I was happy with the setting WIFI_PS_MIN_MODEM however the mode WIFI_PS_MAX_MODEM seems to be mandatory for my application. So I tried to change the setting just before joining an access point and the device managed to join it without crashing but it messes a bit with my application. I'...

Re: Power management fail after WiFi join

I managed to narrow down this issue to the WiFi power save settings. First, I wasn't setting the listen_interval in my WiFi configuration (wifi_config_t) so I added it and set it to zero. It wasn't working either so I tried the other power save mode (WIFI_PS_MIN_MODEM instead of WIFI_PS_MAX_MODEM) a...

[SOLVED] Power management fail after WiFi join

Hi, I have an application that require the power management features. I was using esp-idf 3.1.1, seeing that in 3.1.3 release note there was a "Fixed crash during simultaneous use of Wi-Fi, Bluetooth and modem sleep" I decided to upgrade to this version. However I still have this issue, which will h...

Re: mDNS time to live

Indeed, the protocol must be prefixed with an underscore. I ended up using Bonjour Browser on Windows to see if my service was correctly registered and it works far better than Service Browser on Android. There should be no problem now.

mDNS time to live

Hello, I am using the mDNS APIs however I don't see any option to set the TTL of my mDNS service. The service is visible on an Android smartphone with the application "Service Browser" but only for a brief period of time (I would say one second). However I need my service to be always visible and I ...

Re: Sleep modes and Wi-Fi

Thanks. I also found in the forums a really interesting document about low power solutions : https://www.espressif.com/sites/default ... s_en_0.pdf

But it's only for the ESP8266, is there any other one for the ESP32 ? I couldn't find it.

Re: ESP WROVER KIT PCB Layout

It's larger than surrounding resistors and is marked with "0". Thanks ! Of interest, how did you find the link to dl.espressif.com/doc/xyz in your first post? We used to mirror docs on this site but moved to docs.espressif.com in late 2017. Will set up a redirect but also wanted to check if we have...

Hello, I'm trying to find the PCB layout for the ESP WROVER KIT v3 but I can't find it.

I'm searching for the R...
