[QUOTE="Dronason, post: 56222, member: 553"] We were talking what OTG cable impact, so it is no really same subject. In theory you are right, now in practice itdepend if that noise is visible by the link to RC in term of amplitude and frequency. The key element is the bluetooth. The wifi is not generating signal (if you don't set it an access point), the cellular link is on a totally different frequency band. The bluetooth is generating disturbance on all channels of 2.4G wifi band. It will affect the Spark at power up as it will have the tendency to select 5.8G instead of 2.4G because of Bluetooth. During connection. It can also create hang and disturbance if the band for Spark-RC is 2.4G when the Spark is at some distance and its signal decrease at RC reception. So with Spark, any Bluetooth device is your enemy, with OTG cable or not. [/QUOTE]
