<![CDATA[Limited to 16 widgets on initialization]]>I am in the process of porting my milling machine controller code and integrating it with the basicBLE example. The controller has a total of 60 functions and the GUI design uses around 130 widgets. I am porting the functions one at a time and it was going well until I got to the 8th function. The initialization sequence stops after displaying 16 widgets. I tried adding 100 ms and then 500 ms delays between sendMsg groups, but still only 16 widgets appeared. I added more widgets and commented out some of the previous ones, but no matter what combination I tried, only 16 widgets would appear. The code continues to work with the first 7 functions even when the remaining widgets fail to appear.

Any ideas? I'm not sure where to go from here.

I removed the previous BLE device and created the new one and everything now seems to be working as expected. I now have all 109 widgets on my main screen working and I am well into porting the milling machine controller code to the new GUI. Thanks a lot for your help. Hopefully it will be smooth sailing the rest of the way.

Are the service and characteristic uids the same as the one from before?

I suggest you unpair and remove the device (Android settings) then also remove the device from GUI-O and try pairing again. Maybe also try changing the BLE name in the source code...

I copied the code you suggested, made the required changes/additions: (I changed lines 55 & 125 to use "String" instead of "std::string" & I replaced lines 9-12 with the first 37 widget strings of my UI design.) I loaded the code to my ESP32 and then tried to connect BLE from the GUI-O app and got error message "Invalid service error:"

I'm probably doing something wrong, but with my limited knowledge, I don't know what to try next. Suggestions?

please check this thread:

https://forum.gui-o.com/topic/231/issue-on-sending-widget-on-init

At the bottom you will see a "non-blocking" code BLE code... Can you try it?

P.S.: Adding some delay does not work, since BLE events are not processed I believe...

Best regards,
