Hi, I'm developping a project that requires to connect with ble on two sensors, manage a display, and when needed, start a softAp for file transfert on microSD. Ble client and server coexist fine. My display too. I'm at the step tonintegrate the softAp example code into my project and i meet issue t...

Hi, I need to read each second my sensor . esp32 is ble client. i want to use timer each second that read ble charac. I don't use notification to save batterie, as i know i have to read each second. All example use notification. I call in timer : esp_gatt_status_t status = esp_ble_gattc_read_by_type...

Hi, I'm trying to connect to my custom sensor that is the BLE server. My esp32 S3 is the Ble client. I'm using example ble multiconnect example, where i merged ble_client _security into it. I can properly discover the service I need, and the good characteristic too. But when I try to write to it I g...

Thanks a lot for your reply,

I measured the consumption, and with this exemple i get 100mA continous.

It is really too much for my batterie application even if i play with sleep mode.

Is it possible to reduce it drastically? ( around 30 or 40mA should be good)

No body specialist of ble ?

Hi esp32 expert :P I'm starting my new projet based on three esp32 and their BLE module. Purpose is two have two peripheral esp32 sensor modules that connect to a third esp32 central display module. For peripheral connected to sensors, i wanted to use gatt_server_service_table example project to sta...

Hi every body, I'm developping an app with i2c device, and i am really surprised to see my signal really not square, it is like there is a capacitor effect on the ligne. I also don't understand why signal frequency equal around 73khz, while i set 100khz. I am connecting on pin 19 for scl and pin18 f...

Thank you very much it works !

How is it possible that this function require so much space ?

Fix buffer size ?

Hi Every body, After succesfully installed eclipse and run few examples "by hand" , i'm starting a simple program. I started from blinck exemple, and add a second tasks. Led connected to pin5 blinks well. My second tasks executed each 1 second a printf("hello"): void my_task2(void *pvParameter) { wh...

hi,

I found the issue.

In my case it was really linked to USBPcap installed by wireshark.

I just installed it in winodws in Control Panel\Programs\Programs and Features.
