http client: expected round trip time

Hello everybody, I am interested what the typical round trip time for a single http request in "normal" wifi conditions is (not https). The reason why I ask is as following: * 8 out of 10 requests are being dealt with in less than 250 ms. * 2 out of 10 requests takes really long (>5 seconds). My que...

HTTP is very slow (>5 seconds) after first deepsleep

Hi everybody, I hope you are doing fine. I am having a strange problem: I have an app that is woken up a couple of times a day. It then connects to WIFI and connects to a REST API (http) which I provide. After successful connection to the REST API the device falls to deep-sleep again. I noticed a ve...

ESP32-(S3) WIFI auth timeout

Hello everybody, I am working on a project with the ESP32-S3 which relies on a fast wifi connection. Sometimes the wifi connection time is around 200ms which is very good but sometimes it is around 3,7 seconds. When the wifi connection time is 3,7 seconds the order of events is always the same: * Wi...

Re: ESP32C6 LP power consumption

Hi, sorry for the confusion. Everthing is fixed and the LP consumes 50uA @5ms wake intervall! The problem was that I was still using this code snipplet (taking from an ESP32 ULP FSM programm): ESP_ERROR_CHECK( ulp_load_binary(0, ulp_main_bin_start, (ulp_main_bin_end - ulp_main_bin_start) / sizeof(ui...

ESP32C6 LP power consumption

Hello everybody,

I am measuring 1,5 mA of ESP32C6 WROOM module (without Dev Board) for deep sleep and LP "powered down / halted".

This value seems quite high. Therefore my question: Is this value realistic?

Best regards,
Christian

WIFI connection speed

Hi everybody, I am using ESP IDF together with an ESP32 WROVER module. The connection to my access point usually takes 3,7 seconds but sometimes only 250ms. The reason for the 3,7 seconds is that the first connection attempt fails (see hereunder - the so called WIFI_EVENT_STA_DISCONNECTED event rais...
