nRF51822 ( ADA2267 ) no response to AT-Commands from Terminal

Post by James1963 »

Hello,
I got an Adafruit Bluefruit LE Friend - Bluetooth Low Energy (BLE 4.0) - nRF51822 ( ADA2267 )
I connected it via USB to my WIN10-Computer and send AT-Commands from a Terminal-Program to the nRF51822.
I see the yellow LED wenn the terminal is sending but there is no response from nRF51 to the Terminal. When I use the Android-App there is a connection established between APP and nRF51 and I can see the sent Text from the terminal. When I send Text form the APP to the stick I don't see anything (no yellow LED and no Text in the Terminal).

When I try to make a firmware-update (in the APP)

Updates->
Version 0.8.1

Download Init file
Starting DFU
Starting bootloader
Connecting..............................................

Upload failed
GATT ERROR

Who has an idea?

Thanks in advance.

BR James
