08/03/2025, 10:17 AMI 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'f

08/03/2025, 1:56 PMCan 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.

08/03/2025, 3:57 PMThe 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, ...)

08/03/2025, 4:06 PMCurrently 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.

08/03/2025, 8:22 PMMaybe have a look if Bluetooth works. If not, then it's almost certainly the antenna

08/03/2025, 8:24 PMCould be the connection/trace to the antenna

08/04/2025, 4:10 PMIf the Wifi of ESP32-C3 is not working properly what option exist then to debug with jaguar ?

kasperl
08/04/2025, 4:18 PMYou can connect via a serial link and use Jaguar over that. Would that work for you?

08/04/2025, 4:23 PMIn 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 ?

08/04/2025, 4:24 PMAs Kasper wrote: you can use a serial connection to interact with the Jaguar service.
floitsch
08/04/2025, 4:25 PMAlso, if 'scan' doesn't work, you can set the target device with
jag scan <ip>jagk
kaxori
08/04/2025, 4:26 PMThe device never gets an IP.

floitsch
08/04/2025, 4:27 PMSince 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.

08/04/2025, 4:28 PMHow can I install an application / container via serial connection ?
f
floitsch
08/04/2025, 4:32 PMIt's a flash-option.
floitsch
08/04/2025, 4:32 PMI think we have a document explaining how somewhere, but I can't find it right now.
floitsch
08/04/2025, 4:33 PMBefore going into details: does your esp32-c3 have an uart-usb converter?
floitsch
08/04/2025, 4:33 PMif not, then things get more complicated.

08/05/2025, 2:14 PMsame behaviour now detected for ESP32-C3 devices

08/05/2025, 2:15 PMweird.
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.
k
kaxori
08/05/2025, 2:17 PMok, could be a reason - will check my fritzbox
kaxori
08/05/2025, 2:18 PMthat makes sense because previously used devices don't show that error
f
floitsch
08/05/2025, 2:19 PMI would just enable the hotspot on your cellular phone. -> completely different router.

08/05/2025, 2:29 PMThank you - that was it
kaxori
08/05/2025, 2:29 PMI need an extra router for iot
