Freeze during put request

Official Hardware MKR Family MKR GSM 1400
4

thanks for your reply @sandeepmistry :slight_smile:

For information, here is another sketch with a custom PUT Implementation, without using ArduinoHttpClient library, as was done in the code linked in the previous message from my friend @Marcussacapuces91.

It seems that this custom implementation of PUT is working better, nevertheless, it is still freezing after a random number of request...

NOTE : I am using a LIPO 18650 1S3P 7800mAh
