Using PyCom boards with Arduino IDE

[jmarcelino]

@volodymyr
Thank you for your post. Yes it's possible to run any ESP32 environment such as the Arduino however this isn't officially supported by Pycom.

[Volodymyr]

@jmarcelino Thx. Updated my post to reflect this.

I'm not sure if topicstarter is still on Pycom, but I can't seem to get this to work. The first example doesn't build because of the FastLED library, but I can make it a hello world that just prints over serial.

So the arduino part works. I do have a problem communicating with the LTE modem tho, as in, it doesn't reply at all. Did something change in firmware on the fipy/modem/...?

thanks @Volodymyr for you post, i'm trying to see if i can use lopy4 with the arduino ide (or platformio) and i wonder where to find the doc or the code to run sigfox functions in cpp. Can you give me a hint ?

Has anyone had success with this? When running the above code, I get an "OK" in response to "AT" but every other code that I've tried results in an "ERROR" response from the modem.

[Lonefish]

@mattt I never even had an OK back. Did you use the exact same code?

[mattt]

@Lonefish I tried using that code and the code in this pull request against the TinyGSM library, same result. Almost like the modem is locked until it receives a certain command.

I did have to add #define SerialAT Serial2

Have anyone managed to do it with a Gpy ?, I have been trying without success

I am defining the UART pins as :

#define LTE_TX    23
#define LTE_RTS   18
#define LTE_RX    5
#define LTE_CTS   19

That seemed to work indeed! Sending AT+CSQ replied with 99,99 which is no connection. Haven't tried it any further, but it's more than I had a few months ago ;) Thanks!

EDIT : There was no antenna connected nor was there a SIM inserted, so the 99,99 is logical.

[Volodymyr]

@Lonefish I'm wondering if you got this working ;)
I have updated the OP use the Serial2.

[Lonefish]

@Volodymyr I'm restarting my efforts to get this working again. Have been jumping from POC to POC. But we're switching to esp-idf instead of Arduino. Although, once it's working in esp-idf, it'd be an easy port to arduino back probably.

ATM I'm still at the "having communication" part, no actual internet connection yet, but just started working on it again.

[Lonefish]

I'm using this library at the moment, I can attach and connect to the network, but my efforts fail when I want to do some actual calls to servers. I don't seem to have http-traffic:

@Lonefish Ever get TinyGSM working? I need to sent CoAP UDP messages with it. I've used TinyGSM with other Arduino computers on standard ublox cell modules but new to narrow band.

@Lonefish
Hello, did you finally able to use TinyGSM with FiPy or GPy in order to call servers?

[Clemens]

Would be also interested to use FiPy or GPy with TinyGSM for Arduino

I'm getting this error whenever I try to compile anything for the GPy:

[15975] Error loading Python lib '/var/folders/57/hyd6ntr1233_x_brscxdp8480000gn/T/_MEI7xbrkg/libpython3.8.dylib': dlopen: dlopen(/var/folders/57/hyd6ntr1233_x_brscxdp8480000gn/T/_MEI7xbrkg/libpython3.8.dylib, 10): Symbol not found: ____chkstk_darwin

I have just re-installed Python 3.9.
Anyone know how to fix this?
