Does experimental_ble_app_uart not work without Flow Control?

[Eirik Nobuki Kosaka]

I am trying to make the experimental_ble_app_uart for s110 work using SDK 7.2. It works fine without any modifications, but when i turn off Hardware Flow Control in the UART_init() i am not able to send anything. Does anyone know what the problem is?

The flow control is enabled BOTH on the ble_app_uart which is a peripheral device AND also on the application which acts as central and connects to this experimental_ble_app_uart.

You have to disable it on both sides (i am not sure how to disable this on app)

Out of curiosity, why are you trying to disable flow control?

I am trying to connected an s120 device with the s110 device with direct UART contact, and then make several of these units, and trying to make a hop-by-hop network of sorts. Told it was easier to just pass on the flow control since the baudrate wasn't as high. As i understand it, there really isn't any need for flow control when the project doesn't do much more than the basic example. But I am new to this, so if you have any comments feel free to speak up! Anyway thanks for the help, i guess as long as no devices uses flow control it should work?

Yes, As long no devices uses flow control and as long as the speed is low enough to consider overlows then this should work without flow control.
