BlueNRG-M2SP and X-NUCLEO-BNRG2A1 not working on neither NUCLEO-H745ZI-Q nor custom board
Hi all,
I am using X-NUCLEO-BNRG2A1 + NUCLEO-L476RG as for preliminary test. I've tested the SampleApp example and it works fine.
The final goal is to use the BlueNRG-M2SA in a stm32h753XI custom board + custom antenna. I've tried to generate the SampleApp using cubeMX without success (same issue as descrived below)
By now, I'm trying to use the X-NUCLEO-BNRG2A1 within both, my stm32h753XI custom board and a NUCLEO-H745ZI-Q (this is dual core, but i'm only using the M7-core).
I'm also using the SampleApp example with no success so far.
I configure the necessary EXTI, CS, RESET pins for the SoC as well as the corresponding SPI interface.
I'm always stuck at the same point: performing an hci_reset(); returns me a BLE_STATUS_TIMEOUT on the SPI send command because when doing a CS reset the IRQ pin never gets ready.
/* CS reset */
HAL_GPIO_WritePin(HCI_TL_SPI_CS_PORT, HCI_TL_SPI_CS_PIN, GPIO_PIN_RESET);
/*
* Wait until BlueNRG-2 is ready.
* When ready it will raise the IRQ pin.
*/
while(!IsDataAvailable())
{
if((HAL_GetTick() - tickstart_data_available) > TIMEOUT_DURATION)
{
result = -3;
break;
}
}
if(result == -3)
{
/* The break causes the exiting from the "while", so the CS line must be released */
HAL_GPIO_WritePin(HCI_TL_SPI_CS_PORT, HCI_TL_SPI_CS_PIN, GPIO_PIN_SET);
break;
}Someone else facing this issue with any board ?
There is a similar question here https://community.st.com/s/question/0D53W0000056SoaSAE/what-changes-need-to-be-made-to-run-the-demo-application-sensordemoblesensorapp-on-acustom-board-with-bluenrgm2sp-
but no one is answering.
Any clue?
Thanks in advance
