CC2540 UART 0 alt1 setup Instead of USB for CC2540 USB Dongle
I am working about 2 Months on a project that is under a professor. Project is a from NIF(National Innovation Foundation).
It is about same as a recently famous Tile Device (lost found or object locator) I call it object locator.
TI is based on similar technology developed based on Bluetooth that is BLE (Bluetooth Low Energy) or BLE 4.0
TI(texas Instruments ) have developed an SoC based on BLE . I am using CC2540 for similar application to Tile.
First the thing I wanted was to setup Dongle to UART so Icould connect it to UART of Arduino as to make a independent Device from computer. In the Btool I saw the Communication (Rx/Tx Dump) so I had to first do bridging to a FTDI and setup dongle to uart connected to bridge and then test it to BTOOL.
I wanted to use the same project HosttestRelease but wanted to use dongle as a network processor to Arduino to easily prototype the device to show it to the NIF.
So I had a PC setup for the Embedded Workbench after I used the software in my laptop(to TI people can the ble stack be used with other open source IDE's??) . In the project HostTestRelease,
In HAL>Target>CC2540USB>Config>hal_board_config.h
Line No 336 will be a #defined HAL_UART_ISR 0
set it to 1
just in next line #defined HAL_UART_USB 1
set it to 0
Now I wanted to not have a UART flow control or CTS and RTS cause I wanted to use it with arduino I don't want to waste pins of arduino's
for switching CTS and RTS pin off
go to NPI>npi.h file in that at line 77
there is a #defined NPI_UART_FC TRUE
setting all this will get your UART 0 to work on Dongle's I/O port's First and second pins P0_2(Rx) & P0_3(Tx)
There is one more setting to set the priority to UART 0 but I am not remembering where , I was something that I had to set to 0x00 to use UART 0 and that thing was not defined in the file it was in ISR's Method and was shown as error while compiling if in case u get it please post it in comments and I hope this post will help others cause I was also having trouble for 2 days because of no proper guidance like that in AVR atmel case ... Thank you all.

| this is setup for testing if the Uart works or not I have not connected arduino i have taken out chip and just used the board to make a UART bridge to test it with Btools. |
