I have an ESP32 running as WiFi AP and running an HTTP server using the IDF HTTP Server Component. I keep getting request failures with the warning messages: httpd_txrx: httpd_sock_err: error in send : 104 httpd_txrx: httpd_sock_err: error in recv : 104 these don't happen on every request, and I thi...

To form a connection, your client must be scanning while your server is advertising. Advertisements are sent at intervals, so you could have for example: A client scanning constantly, with constant radio activity, meaning constant power use. A server advertising at set intervals, with radio active o...

The DevKitC does include a WROOM32:

The ESP-IDF Command Prompt should set up your paths so that you can compile projects anywhere, what happens when you try to compile something in a different directory?

Probably too late to help you, but for anyone else finding this thread:

Calling uxTaskPriorityGet() from a BLE event handler returns 19, which would make sense with what f.h-f.s. said about going over 18 for other tasks

Could somebody explain the difference between ESP_GATTC_DIS_SRVC_CMPL_EVT and ESP_GATTC_SEARCH_CMPL_EVT. According to https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/bluetooth/esp_gattc.html: ESP_GATTC_SEARCH_CMPL_EVT = 6 When GATT service discovery is completed, the event comes ...

Thanks for your reply... didn't really have anything in common as far as I could tell. I've got the functionality I need working now more or less, but I pretty much have to restart from scratch. It seems some things persist (GATT & GAP callbacks only need registering once at the start) but others do...

I have an application which uses BLE and want to place the ESP into light sleep. I know it's not possible to maintain any BLE activity in light sleep mode, but should it be possible to disable bluetooth and re-enable the same configuration later, without having to re-initialise everything? Calling: ...

I'm trying to make a program I've written support multiple client connections to different servers. I understand that each connection needs a separate app to be registered. My process is this: Perform a scan Application requests a connection to a certain BDA from the scan results BLE code creates a ...

As my original question stated:

Anyone have any idea what I could to minimise this latency (other than setting connection parameters)?

I'm looking for factors other than the connection parameters which may affect the latency, as I've already set these parameters to provide minimum latency.
