I have mainly used

-D jag.wifi=false

while using the

run

command. And just gave it a go while installing a container, however on container restart jag and wifi came back up. Is there a way to either 1) get a container to tell jag to turn off the wifi? or 2) have something like

-D jag.wifi=false

be more persistent accross container restarts? while keeping jaguar running?

Looking at the list of containers in a default toit built fw envelope, I see one called system

system: 
  Kind: snapshot
  Id: 2ee8a16f-3df6-a81f-7174-7347ab9a8108
  Size: 165638
  Flags: 
    - trigger=boot
    - critical

Is removing this essentially the same as building my own fw image without jaguar? (I'm guessing not, as I removed this, and also added my own container, flashed a device and seemingly it doesnt start up)

Before sending to a specific MAC address, pairing must be performed. Repeated pairing will result in an error message. I haven't found a function yet to check whether pairing has already occurred. For this reason, I first delete a possible previous pairing and then create it again. Don't find the solution optimal and look for a better one. Does anyone already have a good implementation?

If a derived class and its base class have both the same function implemented. But if the base calls its function the function of the derived class is executed. How can I force to call the base class function ?

I have added a watchdog to the container now so I expect it wont cause me an issue again, however I'm confused about what has happeend here The script was running, as shown by the INFO log line Then jaguar seems to have a panic,

Routing problem

and tries to reconnect? fails? and backs off? Then I see my container print

udptocsv

after which it tries to emit this over UDP Then there are logs to do with wifi reconnecting? After which jaguar seems to be back up? However the container is then stuck? I guess it is stuck here

socket.send
    udp.Datagram row.to-byte-array address

Or sometimes it breaks out of the loop and works? Any pointers for debugging / whats going on?

Hello ESP32S3 Experts, I use Arduino IDE v2.3.6 to programme my ESP32S3 board. I set its system clock to 10MHz with the official ESP32 board manager. Codes are good and programming was successful. However, my board fell into Super Deep Sleep and cut the power of the USB serial port. Then, I cannot programme it any more. Please help me to wake it up! 😴 👎 My ESP32S3 board have hardware PWK button, Boot button, Reset Button, Flash Button, etc. I think they can cure it. 😒 I know here are many ES32S3 experts. 🙏

this showed up when i run jag monitor

Is there a way to sleep, but not allowed other tasks to run during that period?

#1025033592688087120 How to use ethernet using w5500 custom spi GPIO ?

I have a 15KB PCM audio file that I want to embed with a container. My plan is to have the container send this data to a C service to play to a bluetooth speaker.

Has anyone already implemented something like this and can provide code snippets? The goal is to trigger the smartphone camera with volume-up event.

How to configure wifi and ethernet using static ip

I am aiming to make an ESP32-S3: Appear as a USB Audio Class Device when plugged into a host PC Receive digital audio (PCM) from the host. Decode the audio and play it into a DAC/amp An alternative plan I have looked at would be: 1. USB Audio Class Support use the TinyUSB stack, which is supported in ESP-IDF and Arduino-ESP32 Implement a UAC1 or UAC2 sink device (only needs to receive audio). 2. Audio Streaming Interface The host sends PCM frames (typically 16-bit, stereo, 44.1kHz or 48kHz) over isochronous USB endpoints. define a USB descriptor that tells the host that the device supports audio streaming at certain formats. 3. Audio Output Path Streamed audio is written to a DMA-capable I2S buffer, which outputs to a DAC to the headphone amp Has anyone implemented the UAC2 or UAC1? Something like [UAC 2.0 ](https://docs.espressif.com/projects/esp-iot-solution/en/latest/usb/usb_overview/usb_device_solutions.html#usb-audio-device-solution)

I flashed 4 seeed esp32-C3 with identical flash parameters, but only one connects successfully to wifi. 3 devices report

Did anyone have similar experiences and a solution ?

Hello Friends, I am very confused when I choose mobile network and global SIM card service providers. They said LTE Cat-1 (the slower version of LTE) modem can connect to 4G mobile network. So, how about Cat-M modem? Can it connect to an existing 4G mobile network? Please help me to clarify. 🧐

Hi, lets say we have this task task:: pin := gpio.Pin 2 --output while true: pin.set 1 sleep --ms=2000 pin.set 0 sleep --ms=2000 After a button press(another task or the same task) we need to respond immediatelly, so the sleep here is inapropriate. I have tried with "monitor" Mutex await try-await but I cannot do it. Ok there is the possibility of a tight loop with "sleep --ms=50" but I have hoped for something more elegant

I have some docs that want to do copy paste instructions, and I dont want to update them every time a new version of a package is updated. It is somehting like

sh
mkdir my-x-project
cd my-x-project
jag pkg init
jag pkg install github.com/x-io/toit-x

then

sh
cp ./.packages/github.com/x-io/toit-x/v0.1.1/examples/eink.toit ./main.toit

But I dont want to hardcode v0.1.1 Is there already a command I am missing that might say what is installed and being used by the project?

As far as I can see, there is not enum support in toit. I have a function like this, there for example the

sound-type

field is actually an enum Whats the best way to document that fact? And or is there already IDE integreation and hinting for such as thing?

/**

What is the new location or command replacing /toit/build/host/sdk/tools/firmware?

Hi, I’ve been using Arduino IDE for all my ESP32 projects because of the huge ecosystem, lots of tutorials, examples, and libraries make problem-solving easy. I wanted to try out Toit after seeing the wireless flashing and container based app like approac. But I couldn’t find many guides or examples for common protocols and use cases. I expected more from the official channel, but there seems to be very little. Is there any written documentation or a recommended way for someone coming from Arduino IDE to get started with Toit?

Hi guys I am experiencing an issue with the Bucket class. Usually it works fine, but in one case trying to access the bucket will hang the task accessing it. This happens when our device has lost its WiFi connection. It doesn't matter if I try to access a global Bucket object, a member of a class, or a local object. My next move is to make a centralized class that handles a Bucket object and thus hopefully minimize the Bucket activity. Can you see what can make the task hang like that?

I tried

return

to exit early in one condition from a lambda, But of course

Can't explicitly return from within a lambda

Is there a way to stop execution of a lambda part way through?

We have some code such as this

for i := 0; i < 3; i++:
      leds[i] = gpio.Pin pins[i] --output=true --value=1
      sleep --ms=1000
    for i := 0; i < 3; i++:
      channels[i] = generator.start leds[i] --duty-factor=1
      sleep --ms=1000
    sleep --ms=10000

Where we control an RGB LED. First looping to setup the pins, with value 1 which in this case is LED OFF We then look through to start the generators, and calling .start seems to cause a small flicker once for each color. Is there a way to avoid this / a bug that can be fixed?

I currently check for a device IP with

network := net.open
network.address

or sometihng similar. But this has the side affect of actually opening the network, even if it were nt previously opened. What is the recommended way to check if the device is connected via WiFi, without calling

open

? I also tried

network.name

but this also requires you to get the network first? Do I need to do something at a lower level?

NetworkServiceClient

? etc?

Every now and again I make firmware that is too big

Error: Firmware is too big to fit in designated partition (1844624 > 1835008)

for example Is there a command line tool / way that I can get the size of an envelope file? without having to try and flash it? I thought perhaps

jag toit tool firmware -e apps.envelope show | yq '.Containers | .[] as $item ireduce (0; . + $item.Size)'

, but that returns only

396868

(far below the limit)?
