What is the max BLE throughput between two xenon devices? I’m trying to perform sending data (between two xenons) received from UART. I need to know what speed can I achieve.


It depends on the BLE write size, mainly, but the maximum is around 2100 bytes/second. There’s table here. Note that these are the numbers for Bluetooth LE, not for Thread Mesh. I don’t have a number for Thread Mesh, but it’s a bit higher than that.


I’m wondering why it is only 2100 bytes/second because here: we can see:
