Does nrf5 ble support hid? #7
Comments

There is no ready to use BLE package in Emgo. |

Is it easy to add? And I can help if you could give me a bit of guidance. |

No, it isn't easy... at least for me. The problem isn't higher layers but lowest layer: BLE controller. You need to read:
The problem insist in strict timing. You have to design a state machine that properly handles all cases and you need to write it cleanly in Go. You need a deep understanding of the protocol and hardware. Debuging is difficult, especially if your only tool is Android phone with its HCI logging. There are open source implementations in: MyNewt and Zephyr. The last one has some support from Nordic: https://devzone.nordicsemi.com/b/blog/posts/nrf5x-support-within-the-zephyr-project-rtos I didn't studied their code but it's probably worth doing. There is my proof of concept code in nrf5/blec and an example that almost works. But everything must be be thought over and rewritten. |
