CC1350: Looking for a Mesh-OS that is handy and allows roaming devices....

Part Number: CC1350
Other Parts Discussed in Thread: CC1120, CC1310,

Hi,about 2 years ago we went through a a painful implementation of Contiki/Thingsquare (CC1120 & MSP430; Sub-GHz is a must for us).

Painful because it took some time to get it up and running, without having a decent support,
We also don't manage to get moving nodes in production, because rebuilding routing when moving between motes took up to 30s - so e.g. a fork lift can't stop for 30s. until it has reconnected...
As we are not familiar enough with the fundamentals of Contiki, we couldn't change the code accordingly - if we changed something, we got side effects on other places.
And we are not trustful enough to put such a system into production - being dependent on a system without industrial quaility grade behind.

With CC13xx I have some hope that there is a TI supported framework to adopt a TI supported Mesh-OS without the need to care about the underlaying stuff - like RTOS.
Change some parameters and you are done, being sure TI has verified the rest  :-)

Back to reality: I learned from the experts that Contiki has never been designed for moving motes, so is there an alternative you can recommend?

What about THREAD (sub-GHz...)?

thx. in advance!

    According to my experiences, it always need a period of time to reconstruct routing path for a moving node in low power mesh network. There is no better alternative to make it faster. Thread is based on 2.4G and I see no difference on it.

    YK and all you guys who are familair with Contiki, please give me you opinion:

    a. is Contiki meanwhile something one can rely upon, to be used in industrial environments?

    b. what is the rough estimate on how much effort it takes to get it up and running, based on CC13xx? Given we have substantial experience with former Contiki version, based on MSP & CC1120, but no experience with CC1310

    thx!

    a. Contiki is an open source and it will need to you put lots of efforts to get familiar with it. If you are looking for a quick solution, I would suggest you to use solution provide by ThingSquare which is based on Contiki but they provide professional customizations.

    b. It's pretty straight forward to setup a Contiki mesh using CC13xx which you can refer to  . I suggest that you can buy LAUNCHXL-CC1350 to have some test on Contiki first.
