Other Parts Discussed in Thread: CC2564C
Dear Sir or Madam,
I tried to test the Bluetooth module (CC2564C Dual-Mode Bluetooth Controller Evaluation Module) with the microcontroller STM32F407. For the connection I used the TI Dual-mode Bluetooth Stack on STM32F4 MCUs.
As a first step I checked if the USART connection works without the CC2564C Module. This was the case. I read out the USART3_TX and USART_RX (Pins PD8 and PD9 on the microcontroller board) with an oscilloscope. After that I plugged in the CC2564C Module and tried to read der address of the device with the vendor-specific commands (see: http://processors.wiki.ti.com/index.php/CC256x_VS_HCI_Commands). There is no reaction of the device though the controller sends the right command.
The whole implementation is orientated on the following tutorial: https://bluekitchen-gmbh.com/btstack-port-for-stm32-f4-discovery-board-with-cc256x/
Is it possible that the Bluetooth development board is not working correctly?
Kind regards
