Teensy 4.1 - Support or configuration

[mrweaver]

Hi,
Firstly, thanks for the great work you are doing on these projects! Keep it up!

I am trying to run an example script with the Teensy 4.1 using Serial3. I have updated the defines.h file accordingly, but get the error: "Not supported board or platform! Please check your Tools->Board setting." emerging from ESP_AT_WiFiManager.h:110:4. I am building through Platformio in VSCode. Looking through this header, I see no mention of the Teensy boards. The README for this repo mentions support for a variety of Teensy boards, but there is no Teensy board included in the provided platformio.ini.

Please forgive my ignorance, but am I missing something?

Any help would be greatly appreciated!
Cheers,
Michael.

Thanks for your interest in the library.

Due to some issues with past Teensy cores (too long time ago I don't remember now), the support to Teensy has been dropped from Release v1.0.1.

You can try using the Release v1.0.0 which supports Teensy to see if OK for you.

I'm sorry I don't have time to retest to see if latest Teensy cores is OK now and add Teensy back to the supported boards because ESP_AT command shield is not popular now.

Good Luck,

Hi Khoi,

Thanks for getting back to me. I'll give it a try and see where I land with it. I've made a board that pairs a Teensy 4.1 with an ESP32-C3, so will be interesting to see how far I get before get in over my head (probably not very far in all honesty!).

Thanks again for your work on this. :)

Cheers,
Michael.

If you're using Teensy 4.1 and ESP32, I suggest you have a look at this thread in Teensy forum

WiFiNINA_Generic Library for WiFiNINA modules to support Teensy and more boards

where ESP32, loaded with WiFiNINA firmware, is working with Teensy 4.1, via SPI bus, using my WiFiNINA_Generic Library.

The AT-command is not worth to use as it's slow and buggy. Using it with the most powerful board of Arduino world Teensy 4.1 will destroy the prestigious beauty of the Teensy solution.

Oh, awesome, thanks for the tip. I'll check that out first then. Might need to do a little board rewiring to access the SPI ports but I'll happily bow to your experience in these matters. :D Do you know if the ESP32-C3 has been used with this library too? Cheers, Michael.

Do you know if the ESP32-C3 has been used with this library too?

Not yet, possibly you're first and we'd appreciate if you can share any experience.
If having issue, still easy and cheap to use ESP32.

Oh interesting. Ok, no problem - If I make any headway with it, I'll let you know. :) If I end up redesigning the PCB I made, I'd probably go with an ESP32 module for that reason - out of curiosity, do you know whether any of the ESP32 modules have significantly better antenna designs, connectivity, power etc?

ESP32 has many advantages over ESP32-C3

• More stable and proven (firmware, WiFiNINA, etc.)
• More powerful, larger flash / memory, yet cheaper / easier to buy / find

certainly, if you have must or good reasons to use ESP32_C3, such as low power consumption, etc., you have to keep testing until getting into unsolvable issue, then going back to ESP32 if still have time to do so.
