How to send HID data from the nRF52840.

[powerup]

Hi.

I am using SDK15 and want to control keyboard and mouse using HID with nRF52840.

I used the HID example to verify that the keyboard and mouse work when the button is pressed.

But I want to control the keyboard and mouse according to the flag in "While ()", not the button interrupt.

app_usbd_hid_kbd_key_control(&m_app_hid_kbd, CONFIG_KBD_LETTER, true)

I simply put the above function inside While () but it did not work.

When using nRF24LU1 +, I used "hal_usb_send_data" function to send 5 bytes of data including ReportID. I wonder if nRF52 has same function.

Thank you.

Hi,

 

This call will send the same key over-and-over, without no RELEASE key being sent over the bus.

Have you tried alternating between sending the last input bool as true and false? This should generate a release_key transfer.

 

Best regards,

I put nrf_delay_ms () function between True and False.

I removed delay and it works fine.

Thank you.
