Hi,
I need to send large data(about 200KB) from android phone to my custom board.
Connected like this :
Android Phone ->(BLE) -> nRF51822 ->(UART) -> Custom board.
And I'm using ble_app_uart(SDK 12.3.0).
I read other posts but most about sending data from BLE module.
Now I just send data with no flow control or something and I have some problem.
My app is based on UART app in nRF Toolbox.
On Android app, I just read data(hex file) and send.
I want check if it's okay to send data. If okay, send data. If not, wait until okay and send data.
I need some guidence or references.
Thanks for reading my question!
