Re: "Sleep" mode in which IRAM and cache are preserved

Im not sure what you are trying to do, but did you try to use light sleep mode?
It will stop executing code on CPU/s, which will decrease a bit power consumption, and will keep all data in RAM.
All you need to stop wifi before enter light sleep mode to turn off radio.

Re: Help: NimBLE Characteristics Properties (Flags) Aren't Properly Applying From ble_gatt_svc_def

Yes, it is not obvious but its annoying during development until you learn it hard way. Another option is to use "forget LE device" on iPhone. Its somewhere in there, but honestly i dont know where. You can also try to connect with nrf connect and use option to refresh services with "discover servic...

Hoping that it might nonetheless spare someone else some time, I do not delete my question and post the simple answer: The esp_http_client_config_t has a buffer_size attribute (that de...

Re: bogus sdkconfig changes

This is not a problem with line endings or similar problems. Obviously something is enabling and/or disabling some options in Kconfig. Do you have some extra build scripts? Maybe rebuild with set-target is doing this? Its rather not possible, but different targets may have different default sdkconfi...

Re: Publishing Messages in Mesh Network

Hi, its not that i dont want to help you, but i believe it will be faster and with better results to you when you start from scratch. - grab espressif example - in custom callback (esp_ble_mesh_register_custom_model_callback) just print logs for event and opcode to see what you are receiving and to ...

Re: BLE 5.0 or 5.3 stack needed in ESP Wroom 32 E

You should read that news.
BLE 5.0 certification is due to ble mesh support. There is no long range, 2mbit PHY etc. Those are only available in newer chips like S3, C3, H2.

Re: Publishing Messages in Mesh Network

First, I don't understand why Sensor Data doesn't match the Message field. Also, what is this warning message about outbound bearer? I thought that 0xFFFF refers to all nodes in the network, but when I try to handle the publish message in the client code, it acts like no message has been received a...

Re: Issue with ESP32 OTA Connection to AWS S3

Thank you for your input. While I understand the concern about ensuring the WiFi connection is fully established before initiating OTA, I've verified that the WiFi connection is indeed stable and operational. Despite this, I'm still encountering the "ESP HTTPS OTA Begin failed" error. Are there any...
