Nextion HMI 2.8" LCD - APC220

Hi

I bought two APC220 modules with the uart-usb converter. I have been tried to transmit using a NEXTION HMI LCD 2.8" with the APC220 and i tried to read in my pc with the other APC220 module and the uart-usb module but i haven't gotten it :/

i don't know whats is the problem, i connect the RX APC220 with the TX NEXTION, i submit 5 V to the APC220

also, i have programmed the two APC220 modules using the APC22X_V12A.exe and i don't have problem with it.

i only transmit "123" , is necessary that i use the page break "\n" ?


Please help me

Attached the NEXTION LCD electrical characteristics

PD: My Nextion HMI LCD works correctly, it has tested with other interfaces
