nRF51 SDK - S110 SoftDevice
|
If you want to use a BLE SoftDevice in applications that cannot be ported to nRF51, for example because they use specific peripherals or need more resources like RAM, flash memory, or CPU speed, you should consider using serialization.
The SDK provides a sample serialization setup consisting of two nRF51 Development boards. One of these boards serves as application board and hosts the actual Bluetooth application. The other board serves as connectivity board and supplies the radio connection. The application board with an nRF51 chip is provided as a reference only. You will need to port the serialized application to the microcontroller in the target system.
The sample serialization setup supports two physical transport interfaces: UART and SPI. See Figure 1 for an illustration of how to connect two development boards as an application board and a connectivity board supplying a UART connection.
Figure 2 illustrates how to connect two development boards as an application board and a connectivity board supplying an SPI connection.
Prepare the connectivity board by performing the following steps:
Physical transport layer | Example name |
---|---|
UART | ble_connectivity_ s110_uart_pca10028 |
SPI | ble_connectivity_ s110_spi_pca10028 |
HCI (reliable UART) | ble_connectivity_ s110_hci_pca10028 |
STM_UART (only available for Heart Rate Application) | ble_connectivity_s110_uart_stm_pca10028 |

The application board does not need a SoftDevice. Prepare the application board by performing the following steps:
