Re: Using ESP SDK API call "system_phy_set_max_tpw"

ESP SDK API call "system_phy_set_max_tpw" does seem to work. Earlier I was Windows provided tools to detect the signal strength, which I am not sure if I can rely on. With two ESP12Es I can at least see signal strength vary between -18dBm to -45dBm for values of 1 through 82 to the API call when the two are very close to each other.

For now I believe this is a non issue for me. I will continue to experiment to learn the characteristics of the ESP12E antennas at the level possible for me. It would still be interesting to hear if anyone else has done similar experiments and have specific values that they can share.

Using ESP SDK API call "system_phy_set_max_tpw"

Not sure if the readers from this forum also are members of esp8266.com forum. Perhaps my question is more relevant here, so re-posting the question (http://www.esp8266.com/viewtopic.php?f=5&t=9039) here:

Is there any specific order in which the API function call "system_phy_set_max_tpw" needs to be invoked? Is it known to work at least in 1.5.2 version of the SDK? I tried before and after starting 8266 as an access point, and as a client. I tried setting the power with value "1" as well as "0" to see if I can see a lower signal strength on a Windows/Linux Wifi connect, but I still see full strength for the signal.
