Hi Folks
At the moment I'm very busy with the C5.
The little one is amazingly good and at the same time you expect more and more and go into areas that are not yet covered and bump into things here and there. (When is the MP time coming - I want more, we are eagerly waiting for it
)
After breaking firmware and time-consuming checking and testing, I have created my own small program specially tailored to the C5 on the desktop of a tried and tested IDE since my youth in order to test recurring processes more quickly. You find a screenshot bottum attached, If there is interest in the program, I can also upload it, the created FW image goes to the **knowed repos**
A small video was created for this - which was uploaded to the ESP32 channel, if you are interested you
can find it here. Nothing special, just shows that 5G works as far as the current state is concerned. A bit of a color spruce up - but that's not really my thing - I mostly just focus on the functionality - hope it meets the general mainstream requirements
As I also encountered various problems with the preview factory firmware and the example iperf did not compile as desired with my installed version of ESP-IDF V5.3-dirty / ESP-IDF V5.4-dirty, the wifi-binary lib and extra adjustments etc., after some advice from espressif support (many thanks at this point) I jumped to the ESP-IDF Master with the current status and version ESP-IDF V5.4-dev-2744-g59e1838270-dirty for this experiment, and I have to say, it helped me to deal with the problems and compile the iPERF firmware after adjustment.
Flashed onto two ESP32-C5-DevKitC-1 and various design PCBs (working so far), I was able to test various things via iPERF that I hadn't been able to do with the factory FW at first, but I am also entitled to apologize and deny blame, as it was a very early stage of development and not all areas that the C5 makes available were covered.
With the current state of things, I was able to test more than before and successfully. Cross-country setups are now possible and work so far. The 5G mode started in my area with 20MBit/s and passed the iPERF test without any problems, there is still potential and I am very interested in further testing and performance improvements, which are certainly far from over at this point in time and in this environment.
- PSRAM support? Yes
- WiFi 2.4 / 5.8? Yes
- 5G AP possible? Yes
- 5G STA possible? YES
- Can the AP be scanned by STA? YES
- Can it also find other AP? Yes
- Can the STA join the AP? Yes
- Country support? Yes
There's still a lot more to be done
Next week it will be a bit quieter because of the upcoming Mid-Autumn Festival and next week we'll go into more detail and the interaction between firmware and PCB and the DevKits. I'm really curious to see how it goes. There will definitely be more PCB designs for various occasions and tests. I'll write a thread about this in the hardware section that might be of interest to some people and then
share my findings here and also in the
target project there **knowed repos**.
If you got an Kit be sure to use 138240 baud instead 115200 in this version with putty or any other TERMprog
this is temporally a need casued a *bit mistake in the efuse* and using 48MHz crystal on this kits / SoC
Wish you a happy mid-autumn (中秋节) festival in advance if we not read/write next days
greetings fly out to friends all over the globe
best wishes
rudi
edit: append info baud and things what was tested
