Apparently, this is quiet common with this kit !!!
I bought 2 of them, I tried the first one and could NEVER be recognised by the NXP Rapid IoT app on my Android.
I am using the NXP app version 1.2. on an Android 7.1.1 on a Motorola G5+. On my cell phone, the Bluetooth setting sees the Rapid IoT kit but not the NXP app !!!!
On another tread, they suggested to downgrade the NXP app to version 11.---. I did it but same behaviour, unable to recognise the kit in the app. On the other hand, the kit works perfect (temp, humidity, pression, ...) and so on,
I thought this could be the device, I unboxed the second one and exactly the same behaviour. Unable to connect the kit to my cell phone.
Very disapointed by this kit.
