Accessing multiple sensors unstable

[ghost]

This bug is based on PR https://github.com/01org/SmartHome-Demo/pull/150.

The BLE connection keeps dropping in <= 3 mins after it has been established via the command line using the instructions here: https://github.com/01org/zephyr.js/blob/master/docs/6lowpan-ble.md

While the connection is established, accessing more than 1 sensor in parallel via the REST API service will cause the micro controller to lock up.

The following config options definitely helped with this. It allowed you to access multiple at once, but if you continue to stress the system (many multi resource accesses) it will eventually lock up again:

CONFIG_BLUETOOTH_L2CAP_TX_BUF_COUNT=15
CONFIG_BLUETOOTH_RX_BUF_COUNT=15

Using these on native Zephyr I was able to use 20, but for some reason ZJS would not get very far at all if they were set to 20.

@uhofemei the patch #1417 may fixed this, please retest

[gvancuts]

Hi @jimmy-huang @uhofemei , has it been determined if #1417 fixes this?

[jimmy-huang]

@gvancuts It's pretty stable for us running OcfServer and OcfSensorServer, but I don't have any setup of the smarthome demo, so it is best for @uhofemei to test it and report back.

Will do.

Accessing an Arduino 101 with ZJS and multi server configuration via the cloud application will bring down the Zephyr device within 5 seconds.

The console output doesn't reveal why it crashed.

[jimmy-huang]

@uhofemei Now with Zephyr 1.10, bluetooth should be much more stable now, please re-test.
