I am using bayangtoys X16 GPS drone. I managed to solder the "alfa APA-M04 7 dBi gain RP-SMA directional panel antenna Wi-Fi" on the board, and it was working absolutely fine. Until, I put hot glue on the antenna's solder to make it more solid.
Since then , when I power on the remote the red light comes on for a second and beeps then it goes off. I removed the hot glue and still its doing same thing..
(That glue near the LED is factory set, it was there since the beginning)
1)I have checked for any short on the antenna's ground and main wire, there is no short there. I have checked the battery and power, and all looks good. 2) Battery are tested for voltage and working fine. The board is receiving proper voltage from the battery, I tested the voltage on the board as well.
Could anyone help me out please!
