Hi,
We are expecting many of our devices to be in close proximity. How can we be certain that when a user initiates a buttonless DFU, that they are uploading to the correct...
Hi,
I thought central is the one which fills up its look up table with 16 bit IDs to keep track of the peripherals. If multiple devices can act as central at the same time...
