    [Teensy 3.6] Max size memory

    Problem resolved using RX1\TX1 at 9600 bauds all work fine, i can receive image from http and display it to FT813. what exactly is Serial5 used for if it does not work, I guess it's just to recover some data or to send some commands. the data must be short ? thanks for MichaelMessner and to KurtE.

    [Teensy 3.6] Max size memory

    Yes BUFFER_SIZE is modified accordingly. I use memcpy because I get binary data, if the character is <32 for example 0 or 2, are not ascii code, suddenly the character string is cut as soon as I receive a 0. I will try RX1, for instance i use 9600 bauds, i can write more 64k, for text file and...

    [Teensy 3.6] Max size memory

    you are right, the AT firmware pushes the response data without control i read data fast to 115200, lose some bytes and time out. I will try to change the baud to 9600 or use the control flow RTS / CTS thanks for your help.

    [Teensy 3.6] Max size memory

    thank you for your answer, it is especially the buffer port serial5 which poses me problem because I use a esp-01 to recover an image via http, when the image is greater than 64k the program no longer works, so we are limited to 64k, I change the value of the receive buffer to 64000 on file...
