Connect to two Dialog IoT Sensor tags concurrently

[Jyro-The-Creator]

Hello guys.
We're trying to connect to 2 Dialog IoT sensors at the same time and save (datalogging) all measurements in a txt file.
Issue started at evothings/cordova-ble#104 (comment) and was transferred here.
The example is here https://github.com/evothings/evothings-examples/tree/master/examples/dialog-iotsensor and is called "Dialog Semiconductor IoT Sensor".
Any ideas?

For another sensor here https://evothings.com/forum/viewtopic.php?t=1795
they seem to be solving it with different sensor IDs, right?

@nbezembinder1 @ @mikaelkindborg
I finally got it, after following the proposed solution of nbezembinder1 from closed issue evothings/cordova-ble#104
I started my own app following starter guide, and now i'm connected with 2 IOTs at the same time, visualizing data from both!

Can't thank you enough guys, both of you for spending time on this. When i have something final. i'll of course share it with the community.

Cheers!

@InventorSector Great to hear your app is progressing!

hey there @mikaelkindborg
many things in the app is going ok, from point zero there's progress of course.

My topology:
Modules send data to mobilephone via BLE, Phone sends data to pc for processing via Wifi.

Now my problem is this:
Testing at low rates, i have to drop below 25Hz for each module, or else it disconnects (one of 2 modules).
For example, when i'm at 10Hz data Rate (sensor fusion = 10Hz = 10 for accel and 10 for gyro), both modules work fine with the app and pc.
But when i go a little higher, one module (maybe both) will disconnect.

Seems that even 10Hz is high for 2 modules to coexist in the app, but the truth is i need maybe more 100Hz.

I guess that for the same reason, when i connect to 3 modules all of them disconnect when i go 'accelerometers on'......

You believe i'm doing something wrong?

Big Thanx

Actually the question in short is, how can i get higher frequency raw data from both modules?..

Hey, thanks for you solution. Now i'm doing the same thing, your research really helps a lot for me. I really want to know, how do you transfer the data from app to pc via wifi? Could you please give some ideas?
