hid keyboard and serial emulation

Good morning,

I must developped a product with BLE module with nrf52840 chip. The product must comunicated with android product and windows 7, 10 and the product must supply the profile HID Keyboard and the serial emulation. It's the first time that developped in BLE, do you have example with 2 profiles HID Keyboard and serial emulation?

I bought an evaluation kit nRF52840 DK and 2 evaluations kit MDBT50Q-DB-40 (raytac module with nrf52840).

to secure supplies we have purchased 220 modules. The first prototype are mid-march! 

Thank you very for help

  • Hi,

    We do not have any examples in our SDK combining these two services, however, we have separate examples for each:

    Combining the services in one example should be quite simple, mainly copying the functions related to the service from one example to the other.

    Let me know if you are facing any specific issues with combining.

    Not sure if you are aware already, but there is no common defined UART emulation/serial service for BLE. The Nordic UART Service (NUS) used in the example above is our custom UART service. The service interaction needs to be handled in applications on the other end of the link, it is typically not supported natively in OSes like Android, Windows, etc.

    Best regards,
    Jørgen

  • Good morning Jorgen,

    OK for the information HID Keyboard Application and UART/Serial Port. In fact for UART emulation the idea is open a virtual COM port  for example with windows 10 and Putty. I will come back to you if I have difficulty to implemented the 2 services. 

    Thank you very much

  • good Morning Jorgen,

    I have a issue with profil uart, I use the application note "getting_srated_nRF5SDK_keil.pdf". 

    The compilation of the sources works fine but when I want to load "softdevices" in the PCA10056 kit, keil v5.30 shows me error: Flash Download

    failed - 'Cortex M4'. For information I don't compile when I select target with flashs140_nrf52_7.2.0_softdevice ? I don't understand where is the issue ?

    thank you for help

    Alexandre
