User defined string by my customers with their laptops

[Tim-TheToolMan]

I am in pre production with the nRF52840. My customers have access to the micro USB port on the device. I want them to be able to define a string for the nRF5 transmitted message when a tamper has been triggered. For example, before they deploy my product, I want them to be able to copy (or send) the string MyTesla to the unit. The have the string MyTesla sent as a message. Do I need a Window app to connect to the BLE interface and place a string in non volatile memory?

Hi,

Do you already have a service that lets a connected peer write to the external flash of the nRF? You can use nrfjprog to write to the memory. See the list of commands here.
