initialization of hcxdumptool 6.2.7-30-g362a817 (depending on the capabilities of the device, this may take some time)...
starting antenna test and packet injection test (that can take up to two minutes)...
stage 2 of 2 probing frequency 2437/6 proberesponse 10  
packet injection is working on 2.4GHz!
injection ratio: 100% (BEACON: 10 PROBERESPONSE: 30)
your injection ratio is huge - say kids what time is it?
