Way cool...
Looking at your RSSI values they are all inside the """blockbusting""", (strong), area.
I am used to working below -120dBm on BWs less the 3KHz wide, often down -130dBm on SSB for SSTV for receiving, and, transmitting at power levels of +50 to 60dBm, 100W to 1KW...
Great work and you are getting it all working remarkably quickly. Kudos...
When I had my Arduino about 12+ years ago or so there were none of these add-ons so we had to design and build our own which, without serious test gear was beyond the average user. A Spec-An like our HP one cost us around 25,000 UKP in the mid 90s which would be needed to create a """clean""" 2.4 GHz signal at 300mW...
<thumbs up> <terrific> smileys here...
