Re: Developping using ESP-IDF

Second the use of PlatformIO.
Sometimes you may need to wait after Espressif releases a new version of the framework but otherwise is it all very straight forward.

How to keep a DNS entry active

I have built a WiFi station (which has a WROVER MCU on board) using ESP-IDF V4.1 which calls the 'tcpip_adapter_set_hostname' within the WIFI_EVENT WIFI_EVENT_STA_START event handler and that seems to be working nicely as I can see the hostname in my home routers list of hostnames, IP address and MA...

esp_event_handler_instance_t not defined in V4.1 - so says my compiler

A few days ago I created a project using the ESP-IDF framework inside PlatformIO running in Atom. At that stage it was ESP-IDF V4.0 and I coded accordingly. Today I saw that V4.1 was released and I upgraded the framework. I also changed some of the code to conform to the V4.1 changes in the WiFi are...

Re: How do I investigate the stack of a task to make sure there's enough space?

I assume you are referring to the some RTOS stack - most have a function you can call to tell you the maximum used to that point in the execution. You will need to refer to the documentation of the RTOS you are using.

Re: Configure GPIO 4 low during Boot

@boarchuz - that code would only get executed AFTER the boot sequence.
The OP was asking about how to keep the pin low DURING boot.

Re: That is a somewhat curious forum here...

It probably means that you need to update your library.
I've had some issues where code examples use a newer version of the library and therefore make API calls that are not in my version.
Also the link that you were provided does contain the name 'Latest' in the URL.

Re: ESP 32 - BLE - WiFi Coexistance

My app scans for BLE servers, connects and reads the characteristic values it is interested in and then sends those to an MQTT hub via WiFi. I'm not doing anything fancy such as turning BLE or WiFI on or off (except to turn both on at the start of the app) but neither am I trying to overlap BLE and ...

Re: ESP32-WROOM NimBle cannot connect multiple clients to GATT server

I believe there is a parameter in the menuconfig settings for the number of connections - have you checked that?
(I say 'believe' because I've not needed to change it but I do recall seeing it there - I'm not able to check right now.)

Re: Can't get esp_ble_gattc_read_char to trigger ESP_GATTC_READ_CHAR_EVT

I think I have found the solution. In the ESP_GATTC_SEARCH_RES_EVT, if the service was one I was interested in, I was calling esp_ble_gattc_get_all_char and then remembered the characteristic handle fr later on. In the ESP_GATTC_SEARCH_CMPL_EVT I was reading the queued up characteristic handle and c...

Re: Can't get esp_ble_gattc_read_char to trigger ESP_GATTC_READ_CHAR_EVT

Thank you for your patch which I have just applied. I get the text "Inside esp_ble_gattc_read_char" but nothing after that. Also, what is the point of the call to 'read char' from within the 'write char' function (the 2nd part of the patch)? I'm never calling write char and it does not seem to be ca...
