Following code is deployed on Puck.

• NRF.on('connect',function(addr) { NRF.disconnect(); });
• nRF Connect application from Android is used to connect to the device.

Expected behavior: No client can ever connect to the Puck and is always disconnected.
Current behavior: On the first attempt, the client is disconnected. On the second attempt 3 leds (RGB) are ON for a second and then the client can connect. When connected back to the Puck, the current code to the interpreter is flashed.

Current firware version is 1v91.
