I am trying to connect a AiThinker Nodemcu 8266 to hivemq. I am referring the tutorial
But when I try to generate the certificate using “certs-from-mozilla.py” , I get following error:
Traceback (most recent call last):
File "c:\Users\sri\Downloads\certs-from-mozilla.py", line 28, in <module>
raise Exception("You need the program 'ar' from xtensa-lx106-elf found here: (esp8266-arduino-core)/hardware/esp8266com/esp8266/tools/xtensa-lx106-elf/xtensa-lx106-elf/bin/ar")
Exception: You need the program 'ar' from xtensa-lx106-elf found here: (esp8266-arduino-core)/hardware/esp8266com/esp8266/tools/xtensa-lx106-elf/xtensa-lx106-elf/bin/ar
I checked in my whole system, but there is no folder
The above is too much for the SSL to work properly with limited RAM available. The certificate store processing crashes when it runs out of heap. I managed to get it initialising, displaying sensor reading on an 128x64 I²C OLED display and sending data to a HiveMQ broker by disabling SSL security checking. This is achieved by un-commenting the setInsecure call from the HiveMQ example code.
If you manage to find the archiver, get the file system uploaded, have anything more than the basic example and it is still crashing then please remember to try the setInsecure call for testing.
Hello, @Daria_H I am facing the same problem so I am trying to use the same thread In may case, I followed all the steps with lots of attention. No I don’t have the ar.exe file in my machine. Python 3.11.1 (tags/v3.11.1:a7a450f, Dec 6 2022, 19:58:39) [MSC v.1934 64 bit (AMD64)] on win32 is the version I am using. I hope you can help me with that!
In my case, it was a problem of recognizing the path/ program.
I’ve solved this by changing the script to search for the path I wanted and directly using the binary.
if which(‘xtensa-lx106-elf-ar’) is None and not os.path.isfile(‘./xtensa-lx106-elf-ar’) and not os.path.isfile(‘./xtensa-lx106-elf-ar.exe’):
raise Exception(“You need the program ‘ar’ from xtensa-lx106-elf found here: (esp8266-arduino-core)/hardware/esp8266com/esp8266/tools/xtensa-lx106-elf/xtensa-lx106-elf/bin/ar”)
