Hello! I've been trying to communicate with an NIBP module (UN600F) through UART using an ESP32 and I need some help. I tried making the module take a manual measurement once but then it doesn't start measuring even when I send the proper commands. I'm not sure if the module is faulty or if there's something wrong with my code. I've attached my code below as well as the communication protocol of the UN600F module. Any insight about my code would be greatly appreciated. Thanks!
Does that mean that I have to send the command code and check sum as single bytes? How exactly can I do this in code? I've also attached a command example found in the UN600F's manual. I also tried sending the command code in a single array similar to the example but it still doesnt work.
Hello I've attached the level ranges of the pins of the UN600F. Does this mean that I have to use a level shifter connected in between the TX and RX pins of both the ESP32 and the UN600F? Sorry I'm not that familiar with using level shifters and your input would be really helpful!
Hi! I am currently working on the same BP module for a school project, but I am completely stuck on producing a code to get this module to work as I am totally new to using Arduino! Would you be willing to help me by sharing the code you are using to get this NIBP module to work!
