Compose generally believes that, for whichever docker-compose -p project it's working on, the docker-compose -f Compose file names every container in the project. Compose doesn't track which file a container comes from, only which project it's associated with, and it can't operate on part of the files in a Compose project the way you show.

The first thing this means is that this sequence actually stops some containers:

How to initialize a Queue on a second core of an ESP32?

Asked 2022-Apr-03 at 12:08

Currently I'm working on a Demo program to better understand working with FreeRTOS. Therefore I would like to try to initialize a Queue on my second core(core1). After initializing i would like to add something to it in a 1 second interval and whenever nothing happens I would like to check my queue and work its content off. Everything related to that queue should work on the second core. The reason being that I previously worked on a Webserver which operates on the main core. My future Queue is supposed to work in parallel on the second core.

This is my current demoprogram:

how to implement buttonless Dfu in App (Flutter Dart )without using any library

Asked 2022-Mar-27 at 12:58

i want to use Buttonless Dfu in flutter without any library , there is already one for Android+ios , but i wanted to implement for all platforms , so expecting that i can connect/read/write and set notifications by using ble , is there any tutorial or something if i can implement dfu by using these ble read/write and notifications only

or if someone can list setps like
write command 0x0... to enter in Bootloader
then when device is in bootloader
set notification for 0x0.... characteristics
and and send zip file to .... this char. something like this ,it would be really helpfull

Entering the bootloader

To enter the bootloader using the Nordic Buttonless DFU you need to write to a characteristic of the Buttonless Secure DFU Service which uses the 16-bit UUID 0xFE59. The actual characteristic depends on your settings. The Buttonless DFU can be used with or without bonds and would show a different characteristic for either one. Take a look at the documentation for more information about that.

The protocol to enter the bootloader is super simple:

To enter the bootloader, you need to send 0x01 to the characteristic. You will receive a response telling you the result of the operation. The message sequence diagram shows a successful response which is made of

0x20 -> defines this message as response
0x01 -> the command you requested (enter bootloader)
0x01 -> Success

Take a look the the documentation for more response codes.

Sending the firmware update

There is a very detailed page about the DFU protocol including a part especially about using BLE. It includes a message sequence chart describing the actual protocol where you can easily see in which order your messages need to be sent and to which characteristic.

It's more likely that you are experiencing hardware related issues than software related issues as you imply yourself.

Re-solder the part that broke off and try again. You probably broke of a resistor/capacitor that is used for noise filtering the output (I am not a hardware guy) or something that is vital to regulating the voltage required for the board to operate.

EDIT

As indicated by: https://raw.githubusercontent.com/hallard/NodeMCU-Gateway/master/pictures/NodeMCU-Lora-Gateway-top.png it seems, albeit that board is of a different design, that you broke off a capacitor or diode. Either resolder or get yourself a new one (100nf) or a diode (1N4148)
