I hope all is well. We are currently working with a couple of Meshport Blue units to test the technology before implementation and we noticed that the units do not have the capability to change channels without the Sena App. We just wanted to provide some feedback and share that in our application, devices like tablets and phones are not permitted due to IP sensitivity. As a result, it would be much more convenient to toggle channels back and forth with say 3/4 rapid button presses. We understand this is not currently a feature, but perhaps this is something that may be considered for the future particularly in industries where cell phones and tablets are prohibited. Wishing Sena continued success! Thank you for your amazing products!
