ble_app_uart cann't send data to another phone after it connect to a phone

[Alice]

Hi

Now I'm using the S130 and ble_app_uart.I meet some problem need your help. Firstly,I download the code to PCA10028,then it can connect to nRF UART on the iPhone5S,it can also send data to iPhone5S.After that,I make it connect to nRF UART on the iPhone6,I found that it can connect to the phone,but it cann't send data to iPhone6,and iPhone6 cann't also send data to it.If I want to send data to every phone that the device connect to,how should I do?

Besides,I have another problem.Is there any API that I can know the data have been sent or I can know the fifo is empty so that I can use sd_ble_gatts_hvx to send more data as soon as possible.Because I found that the device will disconnect when I send more data(50 bytes) at one time.Pls give me some good advice on how to solve the problem.Thanks.

Anyone could help me?Thank you very much for your help.

Not sure what is wrong, as long as you are able to connect to the UART device you should be able to read/write to it. Which version of our SDK are you using and what iOS version is this? Have you tried the UART app in nRF Toolbox (This is the latest version that we are still maintaining)?
