The UART/Serial Port Emulation over BLE (examples\ble_peripheral\ble_app_uart\pca10040\s112) includes S112, which can be a good place to start.

Thank you for the suggestions! 30KB/s is an extreme requirement, a basic variation can accept 10KB/s. From this regard, it looks that s112's "send notification throughput" (which is 190kbps over 1M phy) is enough.

Do you know if s112/pca10040 consumes less power than s132/pca10040? To give s112/pca10040 a try, is there a template for pca10040 and SDK16 to start with?

Hello,

The S112 is a smaller (flash size) SoftDevice with fewer connections and directed more towards nRF52810 (PCA10040e) and nRF52811. It is, however, possible to use S112 with nRF52832, but since this device has a bigger flash you will need to adjust the ram and flash size in your project.

Still, for your application with the requirement of 30KB/s (240kbps) throughput, I would recommend S132 using Data Length Extension. See Throughput for S132 vs Throughput for S112

Kind regards,
Øyvind
