Any help appreciated, dont know much about drones.
MJX Bugs 4W crashed. Got replacement arm. In attempting to solder antenna from new arm to board now drone says cant connect to 2.4GHz network i.e. drone wont arm etc… ?
Tried removing antenna (i.e. unsoldering, will try and upload photo of unsoldered points later) but same message. Have I damaged something? Without antenna should it not still connect (albeit with far less range i.e. remote is right next to it?)
Initially failed to understand antenna was (tiny) co ax so simply tinned and soldered but doubt that in and of itself would damage board? Tried stripping and connecting (and holding) centre (main wire?) to one bit and outer mesh (ground) to other (https://oscarliang.com/repair-2-4ghz-antenna-rx/) but still nothing?
Updated image of where aerial was (or where I’ve messed it up!)
Any assistance much appreciated.
Pic before I’d done anything (i.e. removal) will try and upload one of how it looks not i.e. nothing attached.
