Re: DFUseDemo does not see my TinySA
I have applications which use the Bootloader driver.
?
When I try to discover the DFU mode in the TinySA and it does not discover it I go into Device Manager and have to reload the DFUseDemo driver instead of the Bootloader driver.

Re: Can't update firmware
Hey Arnie and others having this problem,? If you are missing the correct driver for the DFU mode when switched to DFU on the device, take a look on the NanoVNA site, message #24620,, from Dave W3MP and Don KB5QR, which addresses this issue and the fix. Apparently the computer loads STM Bootloader rather than the correct ST Device in DFU Mode so the driver has to be updated.?
NOTE: The NanoVNA and TinySA use the same ST Micro software so these instructions apply to both types of units.? It's a great idea to subscribe to both user groups as there are common operating issues between them. Also having both an NanoVNA and TinySA provides a wealth of complementary measurement capabilities especially for the ham or general RF engineer/tech.

Arnie, go to the main TinySA site? Go down on home page to:
Main Subjects in this wiki. Look in the table for Updating the
Firmware and PC SW. Click on either and you will get a link to
Erik's site, for the latest FW:?? and in PC SW
for the TinySA app:?
For your DFU issue, this is a fairly common issue. You say
your device is recognized when you power it on in windows. If so
look in device manager/PORTS and see the STMicroelectronics Virtual
COM Port (COM*) for the port your TinySA shows up on. This will
appear and disappear as you turn the device off and on. Now go to
DFU mode on the device, the previously showing port in PORTS will
disappear and look now in Universal Serial Bus Controllers for "STM
Device in DFU Mode". If you don't see this driver, then you are not
loading the specific driver for the DFU link. The two drivers work
together, one is for the normal interface and the other is for the
DFU .interface.
Take a look, if the DFU driver is missing there are links to
install it either on ST Microelectronics website of in the group
wiki.
Good Luck

When I had this happen, it was a bad USB to USB-C cable. The cables that came with my TinySA and my NanoVNA were both bad.? I bought a couple new cables and it worked fine with them.

James, Here is an Audio noise source that runs on a PC. You can feed that into your audio filter and then connect the output of the filter to the PC mic input and measure the spectra with an Audio Spectrum Analyzer on the PC like this free one: There are many other audio spectrum analyzers to be found on the internet as well as other audio noise sources.??The above is free and simple.? You should understand the limits of your test instruments, in this case, both the noise source and the spectrum analyzer are using the PC sound card with its limitations on frequency and flatness.? You should run a scan bypassing the filter, then connect the filter to see the differance.? You will also need to familiarize yourself with the controls of both pieces of software. Again, just suggestions.? Also, thank you for the hint on the "Art of Electronics" books.? I have purchased them to use as a reference.? 73 Evan AC9TU

One of the nanoVNAs is what you want to

I¡¯m a co-owner of the nanovna-users group and if you join

Hi James,

measuring circuits that do not supply their own RF and
the TinySA is used to measure outputs of circuits that
do generate their own RF.
For what you are stating that you want to do, the
NanoVNA is the best tool.? You can use the TinySA to
do the measurements per the video from Erik.? It takes
more fiddling and may be less accurate.? It also takes
an external noise source to generate the RF for the
TinySA to measure.? The RF generator is built into the
NanoVNA and is calibrated across the frequency range
of measurement within the capabilities of the device..
By the same token, you can use the NanoVNA to do
spectrum measurements with less accuracy and more
fiddling.
I would have less confidence in the measurements that
the device was not designed to do.? With that said, if
you understand the details of the limits of the
measurement device, you can use it.
I would suggest that you read up on spectrum analyzers
and vector network analyzers to get an understanding
of how they work.? This is more so as you are studying
electronics, and a deeper understanding of how the
measurements are made will help.

Hi James,
There are two different "nano" based devices that are cheap and available for RF and RF circuits measurement.? Each has its own strengths and weaknesses.? To simplify (ALWAYS dangerous, so please take with a grain of salt); the NanoVNA is good at measuring
circuits that do not supply their own RF and the TinySA is used to measure outputs of circuits that do generate their own RF.
For what you are stating that you want to do, the NanoVNA is the best tool.? You can use the TinySA to do the measurements per the video from Erik.? It takes more fiddling and may be less accurate.? It also takes an external noise source to generate the RF
for the TinySA to measure.? The RF generator is built into the NanoVNA and is calibrated across the frequency range of measurement within the capabilities of the device..
By the same token, you can use the NanoVNA to do spectrum measurements with less accuracy and more fiddling.
I would have less confidence in the measurements that the device was not designed to do.? With that said, if you understand the details of the limits of the measurement device, you can use it.
I would suggest that you read up on spectrum analyzers and vector network analyzers to get an understanding of how they work.? This is more so as you are studying electronics, and a deeper understanding of how the measurements are made will help.
Above are just suggestions.? Have fun learning about RF circuits and measurements.
