EL15 Support

Discuss the possibility of adding EL15 support to the app

[StepanKoshman]

@maj113 Do you think it is possible to add EL15 support based on the below command repository?

🤔

@StepanKoshman I was unaware of that BT RE work but it looks... wrong on many places, for one the DM40 doesn't use the RFCOMM but BLE so using sockets for that wouldn't work, the RE of the packet also seems to be wrong:

This is incorrect, 14-15 is the main measurement while 10-11 and 12-13 and the two aux values, the reason why that doesn't help at all is because I require not just the packet RE but also the BLE channels/UUID on where it:

1. receives data
2. sends data
3. SERVICE UUID to actually do a handshake with the device

I tried it myself and it did not even work on my end

[StepanKoshman]

Could this help you?

The other issue is my Env not really being made for multiple devices, I just kinda made this for my own DM40.

If someone wants to implement this (or try to) I'll gladly help though

I'd need the UUIDs, sadly not there

Using NRFconnect can give some clues

If it has the same UUIDs (those fffx) it should be somewhat trivial to at least get the BT stack ready for it

I might be on to something (as long as that RE work holds up)

[maj113]

Well at least it's something, will check when I come home what's going on

[maj113]

Yes. It worked. It displays the initial parameters. It displays the temperature. The data is not updated. The modes do not switch.

Does it stop receiving data after you try switching modes? since the app did receive a good chunk of data looking at the Raw packets, when exactly does it stop?

[Znakharenko-911]

Modes are not switched. Data exchange with the load does not occur. Temperature and current are displayed as they were at the moment of connection. No other data exchange occurs.

[Znakharenko-911]

when exactly does it stop?

Only data at the time of connection is displayed. No further data updates occur.

[Znakharenko-911]

Hello. Can we expect further work in this direction?

[maj113]

In the near future after I get the EL15 myself I'll work on this
