v6: i2c slave, wrong order in request-response

Hello!

I'm working on a project where an esp32 devboard should be an i2c slave, answering to requests from a master device.
I noticed, as other users in the forum, that the order of requests and responses is wrong.

My protocol is very simple: master sends one byte, slave responds with one byte ...

esp32s2, SPI interfaces (VSPI, HSPI, FSPI...)?

Hi!

I'm working on a project based on an esp32s2 board and I need to interface with an SD card, using the SPI peripheral.

The datasheet says:

ESP32-S2 family features four SPI interfaces (SPI0, SPI1, SPI2 and SPI3). SPI0 and SPI1 can only be configured
to operate in SPI memory mode; SPI2 can be ...

Re: DFU with Arduino and esp32s2

strange, if I run the same command in a python shell it works fine:

Re: DFU with Arduino and esp32s2

Thanks for your reply! It sounds good... the only problem is that I can't run the mkdfu.py utility on my Windows laptop:

C:\Users\kw\esp-idf>mkdfu.py
Traceback (most recent call last):
File "C:\Users\kw\esp-idf\tools\mkdfu.py", line 25, in <module>

DFU with Arduino and esp32s2

Hi!

I'd like to use DFU mechanism:
https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-guides/dfu.html

to upload my sketches on a devboard based on the esp32s2 chip.
At the moment it seems that a specific menu choice is not available, but is it there a way to do it manually?
For ...

Re: No esp_ble_gap_config_scan_rsp_data() ?

Hi

thanks for your response.
How can I pass the two structs to the driver? I have to call the function esp_ble_gap_config_adv_data(&adv_data) twice?

No esp_ble_gap_config_scan_rsp_data() ?

Hi

from what I could find, it seems that a function to set the scan response data is missing in the framework.
We do have the corresponding event:

ESP_GAP_BLE_SCAN_RSP_DATA_SET_COMPLETE_EVT

and we also have a member (set_scan_rsp) in the esp_ble_adv_data_t struct that it seems to suggest that you ...
