Read multiple lines using UART protocol / uart.readline() or uart.read() not perform it

[diego.cuba]

Dear Micropython Forum,

I would like to read 2 or more lines that are result of response from a GSM board which is receiving AT commands by micropython board,
and for example i need the third line of its response and i'm using uart.read() , also specifying the number of bytes, does not work properly , when i use uart.readline() the same thing it reads until the \n caracter but i cant get read the third line.

Is there any people that can give me a brief solution of it or any topic related with it
Thanks for your attention,

What i receive:

Code: Select all

>>> uart.readline()
b'+CMGL: 1,"REC READ","w49434p41425@4","","17/0'  
  

What i expect receive:

Code: Select all

>>> uart.readline()
b'+CMGL: 1,"REC READ","w49434p41425@4","","17/0'

OK

readline reads a single line. To read three lines, you have to call it three times.

Thanks deshipu but i performed and while true and does not read the third one.

Perhaps the third line doesn't have \n at the end?
