I have a project that uses LG WebOS and we have bi-directional communication over RS232C between the Arduino nano and WebOS operating system.
I am receiving data great and that part is working awesome.
I have a compiled hex file and believe I need to send it in 128 byte chunks.
I'm not sure what the commands are to initiate this and then send it over for it to update Arduino.
Does anyone have any ideas on this and can point me in the right direction?
Thank you for your help!!
