Hi Guys,
I want to use nRF52840 Dongle as "BLE central UART".
In the first step, i used a nRF52840 Dongle with a Bluetooth low Enegy app in a nRFConnet, the result is corret.
but i have to questions:
- How to command a nRF52840 Dongle with a windows terminal ? What command to send to the dongle to detect a BLE peripheral device?
- I am trying to change a firmware into a Dongle, I created a zephir project. I switch a dongle into a bootloader mode. When i want download a firmware into a dongle with app Programmer, i have an error
