Part Number: MSP432E401Y

Connection mode: the board of msp432e is connected to the router through wired connection mode (100M), and another device is connected to the router through wireless mode
Purpose: msp432e to communicate with another device
Problems: 1. Using Netgear R8000 router, msp432e can communicate with another device. 2. Using Huawei, TP-LINK or Netgear R7000 router, msp432e can't communicate with another device, but the board of msp432e can be seen on the router (the router wired network link light is on)

    Hi,

    What are the differences between Netgear R8000 and Netgear R7000 router? We can start with it and try to figure out what may cause the connection issue here.

    Best regards,

    Memory and flash are the same! Both are 256MB memory and 128MB flash memory, and the CPU is the same. R8000 is bcm4709a0 (dual core 1GHz), R7000 is bcm4709a0 (dual core 1GHz) wireless has difference: R8000 uses three bcm43602 (one 2.4G band and two 5g bands), R7000 uses two bcm4360 (one for 2.4G and 5g band), and the other configurations and network protocols are the same.

    Hi,

    What frequency you used on the MSP432E to connect with these routers? 2.4G or 5G?

    The msp432e board is connected to the router through the wired network port, with a speed of 100Mbps. The other device is connected to the router through 5g WiFi, so that the msp432e board can communicate with the other device, and the router is just one of the transmission media

    Hi,

    Okay. But the wired connection should be same on R8000 and R7000. It does not make sense that it wouldn't work on the R7000 router.

    I think so too, but it did happen. I don't know if there is a problem with the configuration of the network protocol layer, because the UDP protocol used in the current transmission is in the process of transmission
