Greetings,
Received two WIFI kits and attempted to install one. I first used solder wick to "pull" the solder out of the pin holes. Both of my RRC's are "Old style" and only have 10 PINS. After I used solder wick I then used a "Solder Sucker" to pull the rest of the solder from the holes so I could visibly see through the board. The only two pins I could not see through were pins 3 and 4. For these pins I tried both wick and the sucker and with difficulty I was able to pull some solder out of pins 3/4 with the sucker but only enough to make an "indent". I then inserted the 10 pin header and continued to heat the holes and set the header into the board. Since pins 3/4 are very difficult to deal with I left a fair amount of space between the pin header and the board so I could solder pins 3/4 from the top as well as the bottom of the board to make sure they have contact. I then installed the wire jumper from pin 8 for the reset signal.
My RRC's have firmware 2.60, installed. I powered up the unit and used the Microbit Manager to connect to the RRC.
Upon power on I get the RED LED on the WIFI board. Success so far.
From the Microbit manager, I then open the WIFI console, when I click scan I can successfully see a couple WIFI networks in the area. If I hit SCAN a second time I then receive the error message "WIFI module not installed". If I power cycle the RRC sometimes I am successful with scanning and other times I still get "WIFI module not installed".
I then attempted to duplicate this process with my 2nd RRC and I also get the exact same results. I am able to scan and see WIFI networks on the first power up then "WIFI module not installed" error after the initial power on.
Conclusion, with two separate RRC's and WIFI modules I get the same exact behavior.
What am I doing wrong?
Thanks, 73
