BlueNRG chip ID is wrong?

rds-tmeyer commented 3 years ago

Hi, As per AN4872, the chip ID for BlueNRG chip is 3 bytes :

The first byte is the "metal fix version", starting at 0x00
The second byte is the "mask fix version", starting at 0x01
Third byte most significant nibble is either 0x2 (for BlueNRG-2) or 0x0 (for BlueNRG-1) and the least significant nibble is the flash size : 0x3 for 160kB (BlueNRG-1) and 0xF for 256kB (BlueNRG-2).

Currently I get 0x00012Ffor a BlueNRG-2.

Currently the expected chip ID is 0x11103 which I can't find any source for.

Thanks for the info! The code clearly does not support that yet.

I guess we can mask away BYTE1 and BYTE2, and add some BlueNRG-1 and BlueNRG-2 IDs (with various flash sizes) to the list bootloader.CHIP_IDS.

I added the 256kB and 160kB versions of BlueNRG-1 and BlueNRG-2 to master.
