Hi,
I need help with latest X-NUCLEO-BNRG2A1 board firmware/software. The schematic available on ST website looks old as it shows R700 but it is unavailable on my board. On my board R117 has a zero ohm resistance connected. The D1 on the board does not turn On after Power ON.
I have purchased NUCLEO-STM32F411RE and X-NUCLEO-BNRG2A1 boards.
The STM32F411 with updated firmware is unable to talk to the BlueNRG2 board.
The D1 on BlueNRG2 board remains OFF. The J10 pins remains shorted. I have tried shorting the J15 pins as well as swapping the J14 connections from pins 2-3 to pins 1-2.
I do have ST-Link V2 debugger with me.
Please help me download the firmware for ST website for the board containing IC: 8976C-BNRGM2SP so that I can use the BLE in different modes. My sample test code executing on sTM32F411 which fails with message hci_reset : FAILED (66)
Please also suggest when and how to use stsw-bnrgui-v471, stsw-bluenrg1-dk, etc. and any other tool.
Thanks and regards,
Rajeev
