Trouble using Bluetooth & WiFi at same time on Android

[MikeDailor]

Hi there,

I am having a very bumpy ride attempting to use Bluetooth LE and WiFi at the same time on Android devices. I am using the Evothings BLE plugin to continuously monitor one or more BLE devices, and at the same time I am using WiFi to continuously report their status and location back to a server. I can do this with no issues on iOS, but on Android it seems like the two technologies are competing with each other and neither one works reliably. If I shut off the Bluetooth, all of the WiFi traffic works fine, and if I shut off the WiFi, I can see all of the Bluetooth devices. But if both are enabled, the BLE device visibility is questionable, and the WiFi traffic may/may not make it to the server. I have tested this on a Nexus 7 tablet with Android 4.4.4 and an LG Optimus Exceed with Android 4.4.2 with exactly the same results.

Any thoughts on this? Anyone experiencing the same behavior? Thanks in advance.

BLE on Android has had varying levels of instability from day one. WiFi interference is a known issue. Nexus 7 is one of the worst. Nexus 5 (LG) and Nexus 6 (Motorola), with Android 5.0, have worked better for me. I've not tested the LG Optimus.

Thanks for the holler back Fredrik, much appreciated.

I am using a Nexus 7 with Wifi and Bluetooth active at the same time and it seems to work. I am running Android 5.1.1 though.

MikeDailor: I'm looking to do something very similar to what you have mentioned in your post. Using Android mobile to connect to a remote device via BLE and redirect the BLE device data via wifi. I'm very new to Evothings and wonder if you could provide me some guidance? Thanks
