nrf sniffer not picking up any packets

Hello,

I am using the nrf sniffer from adafruit to pick up ble packets from my NRF52. Everything has been working fine for the past 3-4 months. Yesterday I wanted to test a new program I had written that allows the user to input from putty terminal through UARTE how many ble packets/sec they would like to send, test duration and TxPower of the radio. After flashing the code and inputting some basic settings (2 packs/sec, for 2 seconds) My sniffer stopped working. I had a friend of mine try the code out on their setup that was working and it too caused for the sniffer to stop working.

I know I am transmitting messages because I have programmed another NRf52 to blink an LED everytime it receives a BLE packet with a specific advertising address. I have tried several different transmission test for example 4 packets/sec for 4 seconds and I see my receiver blink 16 times as expected.

the only thing I can think of is that since I am using a COM port for my sniffer and a COM port for the beefy ftdi breakout (communication from putty -> Tx NRF52) somehow this may have reprogrammed/damaged/ interfered or did something strange to the sniffer.

Any ideas would be greatly appreciated!

I have attached the code if you would like to take a look.
