Pure SPI?

[lorf]

Hi!

Csr-spi-ftdi only implements transport layer of the protocol, You would need to implement it in Arduino (see https://github.com/Frans-Willem/CsrSpiDrivers). On top of that You would need to implement functionality you want (e.g. flashing firmware, controlling the device with BCCMD or configuring it with PS Keys).

Here are some pointers:

• Protocol analysis: https://web.archive.org/web/20190116215601/http://jernej87.blogspot.com/2012/10/csrs-usb-programmer-protocol-analysis.html
• Flash dumper: https://github.com/lorf/csrprogrammer
• BlueCore 4 flash programmer: https://web.archive.org/web/20180125112520/http://members.efn.org/~rick/work/rpi.csr.html
• BlueZ stack has BCCMD implementation over other transports: https://github.com/bluez/bluez/blob/utils-3.36/tools/bccmd.c
• Some useful information may be found by searching for "BlueSuiteSource_V2_5" and "BlueCore BCCMD Commands".

Thank you, Lorf! Would you be willing to volunteer a little more time to help us solve this? We need some hand-holding on this. That would be fantastic, and i'd be super grateful. You’d be helping us uplift teens in-crisis. We don’t have the expertise in-house to follow those awesome clues you shared. We'll list you on our Advisers page. https://boo.ma/advisers The BOOM is a Resident at Autodesk, we won awards from Protolabs and Not Impossible Awards. We're a member of Engineers Without Borders. We've been featured in Make Magazine. Unfortunately, we're not funded, so we rely on volunteers. https://boo.ma/makezine Thx!

i found some additional info that might be helpful, but i'm in over my head. Note, we plan to go with QCC3008, not the CSR.
