ble_app_proximity errors

[Adam]

Hi,

I'm testing ble_app_proximity example (...\Nordic\nrf51822\Board\nrf6310\s110\ble_app_proximity). I'm using Master Control Panel Android app version 2.0.3 and Nexus 5 with the latest Android 4.4.4. I've noticed a few errors that seems to appear randomly.

1. When I try to connect to "Nordic_Prox" sometimes I get Error(0x81): GATT INTERNAL ERROR Error(0x85): GATT ERROR

2. While reading the Tx Power Level sometimes I'm getting Error(0x89): GATT AUTH FAIL, on another phone with Android 4.4.2 these errors also occasionally occur.

Thank you in advance for any advice how to eliminate these errors

Hello,

I am suffering these errors too. Nowadays, I am developing a project using a nrf8002, and either with Nordic App or with my code, these errors appears in my Smart Phone (Nexus 5 Android 4.4.4)

I don't know how to fix them, but in an other post, a Nordic Semi Employee told us that these error are coming from internal Bluetooth Stack. I agree, because of it doesn't matter how you disconnect from your peripheral. Either using disconnect() or close() functions, internal Gatt error will appear. It is a matter of time.

As far I am concerned, Google should fix these annoying issues as soon as possible if they really want develop weareables based on low energy technology. I hope these will fix soon.

Carlos, thanks for the explanation, but if anyone else would like to add something I would be very thankful.
