How do I get multiple different mock barometers?

I think it's more related to allow enough time for people to read the log without flooding it
No, there's more going on than just that apparently. If I reduce their value to zero, it bombs. Reducing short-wait to zero causes the mote to get stuck in a loop somewhere, and reducing long-wait to zero causes the gateway to miss receiving some packets.
If these examples are meant to teach, it sure would be nice if it was documented code!
@NeverDie I am not sure, but I think the mock sketch is meant only for validating new builds of MySensors (by the Jenkins build system connected to Github). It is not included on the build page and as you said it is not documented so I don't think it is meant to teach.
I may be wrong though, I didn't know that sketch existed before you mentioned it.
At almost 1,500 lines it is 10x bigger than most of the build examples, which seems like a very bad idea if the intention is to teach.

This wait() can also help to avoid packet losses due to insufficient power supply when using nRF24.

You mean it needs extra time for the auxiliary cap to recharge? If so, surely we can find a better way to power the radio module that doesn't require taking a breather between packets....
I don't remember how it works with the nRF24L01, but on the RFM69, there's only one buffer for both sending and receiving, so you have to empty the receive buffer before you either send or receive another packet.

@NeverDie a discussion on that topic is underway in https://github.com/mysensors/MySensors/issues/892

In that case the nRF52832 should be faster at emptying the buffer, since it doesn't have to rely on the slower SPI bus. And from what I gather, it can also do DMA's, which could speed things up even further. -

@NeverDie for a node I think the bottleneck is the speed of the air transfer. Sending a message takes about 1ms at the default setting of 250kbps. But a busy gateway might benefit from the higher processing speeds on nRF52832.

Does it default to 250kbps to compensate for the range problems that the nRF24L01 has? I'm planning to bump mine up to 2mbps if at all possible. That might save appreciably on battery life.

I suppose the
wait(long_wait)isn't so bad a power drain if it's actually sleeping rather than busy-waiting for 500ms.

Here is a little sketch that compiles on the NRF5.

#define MY_NRF5_ESB_PA_LEVEL (NRF5_PA_MAX)
#define MY_NRF5_ESB_CHANNEL (76)
#define MY_NRF5_ESB_MODE (NRF5_250KBPS)
Just now noticing that your definitions:
#define MY_NRF5_ESB_PA_LEVEL (NRF5_PA_MAX) #define MY_NRF5_ESB_CHANNEL (76) #define MY_NRF5_ESB_MODE (NRF5_250KBPS)can also be set in myconfig.h.
Strangely, myconfig.h defaults to max Tx power on the nrf52, but not max Tx power on the nrf24. Not sure why, especially since, if anything, the nRF24 needs it more.
So, I just now changed myconfig.h to put everything at max Tx power and 2mbps ota datarate. A lot of the nrf24 fake chips don't even run at 250kbps.

Do mean the fake chips need to run at higher datarate?
All the fakes I've encountered can handle 1mbps and 2mbps.
-
Not sure why, but by upgrading to 2mbps datarate from the previous default of just 250kbps, I'm able to reduce LONG_WAIT to 0 without incurring packet losses. Go figure.
-
For the SHORT_WAIT, 10ms seems adequate on an nRF52832. Not sure where it hangs if the SHORT_WAIT is reduced too much lower than that though.

@NeverDie my question was if thay handle higher speeds better than the lowest since you said "A lot of the nrf24 fake chips don't even run at 250kbps"

I'm not understanding your question.

What does it mean when the Domoticz log looks like this?
