ESP32 WROOM 32 WiFi signal strength - Flowcode V9
Posted: Sun Dec 27, 2020 9:54 pm
Not sure I am correct, but when I run a WiFi Scan then do a ReadSignalStrengthFromScan, I get a number that is way off. If I subtract this number from 256, I get a very close reading to what my Android shows. For example, if I place an AP right beside the ESP32, I get a signal strength of 249. When I subtract this value from 256 it shows 7db (- 7db but the ReadSignalStrengthFromScan does not return negative numbers so you have to add the '-' sign)
So, it is working very well if I subtract from 256. Am I missing something?
