Thread vs BLE Mesh

[wassfila]

@wassfila

I was thinking, imagine 280 end-devices transmitting data to a server by RADIO

Looks that use THREAD on end-devices to transmit using UDP is faster that the server making a BLE SERVER scanning of end-devices making broadcasting...

Right ?

I would say that it is not true. BLE has added a mesh concept to catch up with Thread, and there is no scanning on that mode of end devices one by one, it is similar to listening for broadcasts.
You can search for "Thread vs BLE" to know more about it. My recommendation at the end is the following :

if your devices need to be connected to the user smartphone with direct connection without network infrastructure, then BLE
if devices are permanent monitoring sensors connected to a server, then Thread has a more solid networking due to transparent bridging of network.
I tried to check BLE mesh with IPv6 to compare both, it was much harder at least me, I could not manage, maybe it got easier by now.

Here is a serious and professional benchmarking of 3 technologies Thread, Zigbee and Bluetooth Mesh

BLE make me crazy

Threads much more fast!

You have to be careful of integration differences, according to the silabs study, the difference is not huge.

Is that an nRF52 udp thread listener ?

[tcpipchip]

3 modules sending udp packages :)

With 115200 bps serial port, you could easily have a bottleneck on printing. Using native usb cdc could get faster, but yeah throughput is high.

Hi, all listeners are the NCP on raspberry, yeah, 115200 is a problem
Next step is to implement a node-red application to listen UDP.

[tcpipchip]

My idea is to use 210 threads modules to transmit package each 1 second + some ms, to not allow cillisions

[tcpipchip]

Hi, making more tests, now node-red listening 3 UDP packages, no CRASH

@tcpipchip
congratulation for the great success.
Please keep me updated (but on other discussions tickets) and especially if you need further help with code that I've written, but it feels like that you're the pro now and can even help others ;)
I will lock this discussion because it is deviating from the the topic Thread vs BLE Mesh on which I would not have much to say than the initial provided answer anyway.
