like with firmware adds new but often stops something old to work.... you can always load old version if something doesnt work

@kuriko Thank you for your response. I did this step by step. Deleted record.json res.json After pushing the code, the problem remains the same., error 403 So I Reburn the Core2. After pushing the code, the problem block on Sync screen, error 403 I think there is a problem accessing the file bucket on Alibaba. Or else the load transmitted by mqtt to the device is not what is expected for res and record json. Similar of: https://community.m5stack.com/topic/7652/uiflow-2-0-sync-error

@hacxx Dear hacxx, Thanks for your help.

@PavelNDC Public (red) means that's it's not connected. normally this is an issue with the M5Stack server.

Hello @peolsolutions you are starting to confusing me. Your posts often are quite vague and not specific to M5Stack hardware / software. Also why would you post a very similar response again about a month after your last one? Doesn't make sense to me. Care to explain you reason(s) for doing that? Thanks Felix

There was an update for the UI and now i can burn an image to the AtomS3. Everything fine and thanks for your support and help!

@ajb2k3 Thanks.

@gwky55 Hi, Example in MicroPython: ... def setup(): global wlan, http_req M5.begin() wlan = network.WLAN(network.STA_IF) if wlan.isconnected(): print('Connected') http_req = requests2.get('https://test/test.php?val1=aaa&val2=bbb', headers={'Content-Type': 'application/json'}) print(http_req.status_code) And UI Flow2 [image: 1750496079077-http-get.png]

@ajb2k3 There was no previous firmware that I installed. This was an out-of-the-box installation. I downloaded the latest update - I think 2.2.7 - and that's when the problem occurred. Also, when I went to press burn, there was no opportunity to erase before burning.

The EXTIO2 with three UltrasoundIO devices connected delivers high-performance, synchronized ultrasound data acquisition. Ideal for advanced diagnostic and research applications, this setup ensures seamless connectivity and reliable data transfer. EXTIO2's robust architecture supports simultaneous operation of all three UltrasoundIO units, maximizing efficiency and enabling multi-channel imaging or analysis. With plug-and-play functionality and scalable design, it’s the perfect solution for labs or clinics requiring precise, real-time ultrasound integration and control.

Hi, I had the same issue, but found a solution. I had created the account with a capitalised first letter in my email address, needed to use the same syntax to log in.

The error in the Passive Buzzer Unit is still present. More precisely, this error has been present in all PWM units since version 2.1.8. Does anyone know what has changed since then? Does anyone know how to work around this error, other than reverting to version 2.1.7?

I got it!! Sorry, the trouble was very simple!... If you want, the solution is below: [image: 1746056269421-captura-de-pantalla-2025-05-01-a-las-1.37.42-resized.png]

@m1cr0lab said in Unable to connect with M5Burner: @robski @ajb2k3 Thank you for your answers. I reinstalled M5Burner... But when I went to the online UIFlow 2.0 application, I realized that, like an idiot, I was using my username instead of my email address to log in. Now everything works normally. 🙂 Sorry for the blunder... but I'm guessing I'm not the last person this will happen to 😁 Cheers, Steph ROFL, I think most of us have done that at some point!

@ajb2k3 Does not appear in the device software list. [image: 1746003450972-f9f0fc8e-8c11-4b55-b641-bd539fb14fd2-image.png] [image: 1746004140123-57942492-f2a3-4e19-a5f0-a5d2fb842a3c-image.png]
