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

3 devices report running Jaguar failed due to 'DEADLINE_EXCEEDED'

Did anyone have similar experiences and a solution ?

Can you try with a cellphone (as a hotspot) close to the device and see if that changes anything? Basically, ruling out the router and weak signals.

kaxori 08/03/2025 03:57 PM

The router is ok, there are a lot of IOT-devices working well. And I am only 1 m away. Because I used the same script to flash jaguar on the different devices, I distrust them.
My next approach is to check them with different tools (plattform io, ...)(edited)

Currently I don't see what Toit could do wrong, but if it works with platform.io (or something else), we should figure out what Toit is doing wrong.
Thanks for investigating.

The same result, 3 of 4 devices cannot be connected to WLan.

floitsch 08/03/2025 08:22 PM

Maybe have a look if Bluetooth works. If not, then it's almost certainly the antenna

kaxori 08/03/2025 08:23 PM

I changed the antenna already without effect.

floitsch 08/03/2025 08:24 PM

Could be the connection/trace to the antenna

If the Wifi of ESP32-C3 is not working properly what option exist then to debug with jaguar ?

You can connect via a serial link and use Jaguar over that. Would that work for you?

kaxori 08/04/2025 04:23 PM

In my router the device is visible for some seconds without getting connected. If I scan for it, the device is not found. So how to run or install container an app ?

floitsch 08/04/2025 04:24 PM

As Kasper wrote: you can use a serial connection to interact with the Jaguar service.

floitsch 08/04/2025 04:25 PM

Also, if 'scan' doesn't work, you can set the target device with jag scan <ip>. If the device is visible for a short time, then that command should work. However, you should see the successful connection in the logs. (Without that, here is no hope that jag can communicate with the device)

kaxori 08/04/2025 04:26 PM

The device never gets an IP.

floitsch 08/04/2025 04:27 PM

Since it doesn't work without Toit, there isn't a lot of hope to get it working.
You could still use it with Jaguar through the serial connection.

kaxori 08/04/2025 04:28 PM

How can I install an application / container via serial connection ?

kaxori 08/04/2025 04:30 PM

floitsch 08/04/2025 04:32 PM

It's a flash-option.

floitsch 08/04/2025 04:32 PM

I think we have a document explaining how somewhere, but I can't find it right now.

floitsch 08/04/2025 04:32 PM

Before going into details: does your esp32-c3 have an uart-usb converter?

floitsch 08/04/2025 04:33 PM

if not, then things get more complicated.

Some stores are selling broken ESP32-C3 Super Mini's

2.5-4x worse RF makes them totally useless

No Wifi connect with ESP32-C3 super mini

The first version of ESP32-C3 super mini has a broken antenna design. The workaround is after WiFi.begin reducing the Tx-Power to reduce reflections. WiFi.begin(ssid, password); WiFi.setTxPower(WIFI_POWER_8_5dBm); Then I saw in http://esp32.io/viewtopic.php?f=19&t=42069 the pin 21 issue. I soldered out the single row male pin 21 and remov...

one of the problem devices

kaxori 08/05/2025 02:14 PM

same behaviour now detected for ESP32-C3 devices

floitsch 08/05/2025 02:15 PM

weird.
I would still try with a different hotspot (phone).
We have had issues with a router that "filled up", and also rejected devices that reconnected too often.

kaxori 08/05/2025 02:17 PM

ok, could be a reason - will check my fritzbox

kaxori 08/05/2025 02:18 PM

that makes sense because previously used devices don't show that error

floitsch 08/05/2025 02:19 PM

I would just enable the hotspot on your cellular phone. -> completely different router.
