Hello Everyone,
I am an experienced engineer but actually a beginner with Bluetooth technology. I am working on a project that uses a Fanstel BT832AF Bluetooth module. This module incorporates a Nordic nrf52810 and a Cortex M4 processor. I'm using using SDK v15 and a Segger Development suite with a J-Link Plus Debugger.
Currently, I am trying to modify an example in the SDK which is ble_app_uart_pca10040e_S112. I am having problems getting the pins assigned correctly. I have the BLE radio part working and can connect to a phone app. I can send data from the phone and reach a breakpoint in my code to verify that the data is received correctly. I have however had no luck in getting the UART to pass data to the external pins of the module, nor have I been able to receive data from an external RS485 driver with the uart.. I believe that I have mapped the pins correctly from the nRF52810 to the Fanstel BT832AF module pins.(document attached with pin definitions). The UART is configured, I believe, for 115200 bps, 8 data bits , no parity, 1stop bit
I'm not using a development board but have designed a board for this project that has 1 LED and no buttons. I have also been unsuccessful in getting this LED to turn on which leads me to believe that I most likely don't have the GPIO pins configured correctly.
Things I'm uncertain about:
1) Am i using the correct Soft Device? The S112 is what loaded with this example.
2) GPIO vs GPIOTE and UART vs UARTe for this example.
3) Whether it's pin assignment or UART configuration which is preventing this from working.
I hope I have supplied enough data to describe my problems.
Thank you for any and all help.
