How to write more that 512 bytes to a socket

[mnelson920]

From what I seeing this library writes data to a socket using HEX. Doing this limits the modem to write 512 bytes. I'm trying to write a JSON message that is 570 bytes to AWS. Is there any way to change this limitation?

Hi @mnelson920,

Please share a sketch to reproduce any issues you are facing.

NBClient has a loop now to chunk sending data over a socket that is over 512 bytes: https://github.com/arduino-libraries/MKRNB/blob/master/src/NBClient.cpp#L266-L329

Hi @sandeepmistry : But it's 256 bytes per push, it's more stable with 512

#84

Also the asynchronous socket close is a game changer in stability
