Ble HID key board uisng HID over GATT and UART

Question asked by d.ven on Dec 11, 2015
Hi Guys,

I am currently working on a project to develop firmware for
X-CUBE-BLE1 for the hardware

STM32L053R8 + STM32 X-NUCLEO-IDB05A1 extension board

with the following requirements.
  • Read ASCII chars from a third party hardware over UART
  • Send these chars using HID over GATT from
        STM32 X-NUCLEO-IDB05A1 extension board to IPAD or other Bluetooth devices.

I am new to STM32 and I am struggling with following questions.

1) how do I receive chars from UART

2) how do I sent these chars from UART to HID over GATT using X-CUBE-BLE1.
3) How do I sent UART data from STM32L053R8 to STM32 X-NUCLEO-IDB05A1 extension board.

I have already looked into UART example for STM32L0

Please let me know if there are any examples and also documentation for UART,HID, GATT .

Kind Regards,
