Bootstrap start failed #18

Closed cyliangtw closed 8 years ago

cyliangtw commented 8 years ago

Using K64F & default mbed_app.json, the gateway firmware is "gateway6LoWPANDynamic.bin" from https://github.com/ARMmbed/mbed-os-example-client. Then, got "Bootstrap start failed", details log as below. It seems failed at arm_nwk_interface_up(int8_t interface_id). The same hardware combination could work in mbed OS 3.0 sal-iface-6lowpan-test-nanostack_tcp.

Log:

@cyliangtw Did you let it make more attempts to reconnect ? Channel 12 is right in the middle of 1st Wifi channel , that's why sometimes because of interference you might see the device trying multiple times to connect to corresponding Border Router

@cyliangtw This log looks a bit weird. Rather than bootstrap failure, you should have got something like this:

So you can see that it made at least one try to reconnect. I just tried to reproduce your issue on K64F with Atmel-rf-shield. And that's the result I got. Please tell me more about your setup, components compiler etc. Are you sure you loaded 6LoWPAN Dynamic binary on your BR ? Because to me, it seems you loaded Thread binary there. And that's why your node was not able to get connected.

My mbed-os was downloaded on 07/28, so the log is different from yours. After re-load the last mbed-os and rebuild, it could work, like this. Thanks a lot.

Pleasure is all mine.
