BT4502 transmit from UART to BLE app

Hi Baozhu,

I’ve added delays between the high to low and low to high transition of 5ms. I can now receive data on my phone but it seems to receive twice and every two seconds, even though I’m sending it once and every one second.

You can see in the time stamps above that the first three messages are every second but then it becomes every two seconds.

I then tried to change the CIT to 20ms by sending the TTM command after I had connected and I still get the same issue - messages send after 2s and come in pairs!

Is there anything else I’m missing here?

Thanks,
