Topic: BLE HM-10, Connection issues when to many item on page
Hi all,
I have issues connecting to my HM-10 when there are to many items on the page. All tests where done with the downloaded generated code and no additional programming done yet.
I started with a very simple test 3 buttons and 1 joystick. And it connected straight away. So, I was happy as a small child. Then I designed myself a quite full page 1x Joystick, 1x slider, 5x switch, 2x button 1x LED and 2x text viewer. To be future proof, for my robot project.
Unfortunately, from that moment I always got the error message “Device not reply”, after I successfully entered my password. I tried for hours with different baud rates, hardware and software comms, changing AT+TYPE to 3 and back..... But, I always got the same error message.
Then I found a post regarding disconnecting when too many item on the page, but the issue was more related to the command delay() had been used. But, it gave me a start and I tried with less objects on my page.
And it works again!!! with 1x Joystick (+ centre button) 3x button and 2x switch. When I tried to include text viewer it stopped. Haven’t tried in details yet how many buttons and switches I can include.
Will do more tests.

Question: Are there limits on how many items and which kind I can include on BLE connections?
Thanks in advance for all help.
