I have the Adafruit Feather M0 WiFi. This uses the WINC1500. I am having trouble receiving it when it is placed at its final location. When it’s on my bench it works great. At its final location, sometimes it works, sometimes it works a little, sometimes not at all.
One thing that I would like to try is to check the modules transmission power setting and be able to change it if I so desire.
I have looked throughout the WiFi101 library and don’t see anything concerning the transmission power level setting. I have tried several Google searches and found some mention of it, but nothing concrete enough to write some code for.
That's a big part of the problem. The antenna's final location will be between a Sunbrite TV and an aluminum submarine. I don't know how much of the wifi signal is getting to the WINC1500 from the wifi node or how much is getting to the wifi node from the WINC1500. i can find out, and will, how much signal is reaching the WINC1500. I'm trying to get my IT people to tell me how much signal is being received, but without much success.
The point being, if my project's signal isn't powerful enough, can I up the power level from the WINC1500? i can not find any functions in the WiFi101 library to aid in this. Hence, this topic.
Where in the world are you? Depending on which region the permitted WiFi powers vary. It is probably not possible to increase the power and it also depends on direction of transmission uplink/downlink as the powers could be different. Using proper antennas at each end of the link could gain you a lot. WiFi routers often have terrible antennas.
I just looked at the datasheet on that unit and it has a wimpy wiggly PCB track as an antenna. You need some way to bypass that and use a decent antenna. If the unit is in a fixed position you might use a bit of directional gain as well
