Bluefruit LE Friend

Post by fe8769 »

Hello

I just received my Bluefruit LE Friend. I plan to use it with BTLEJACK
https://github.com/virtualabs/btlejack

As I understand, I need to send their firmware in order to run this tools .I tried to put the Bluefruit LE Friend in DFU mode (pressing DFU) when pluging into PC but only the blue blinking LED is working . Unless with android application "bluefruit" I can't see the Bluefruit LE Friend . I tried 3 laptops linux or windows with the same trouble
With BTLEjack I can see the device in /dev/USB00 . What can I do to solve this problem ? Do I have to buy an extra firmware module and if yes what is the Bluefruit LE Friend pinout ?
Thanks for answer

I'm afraid we don't know anything about that code.

From the Github page, it looks like they support the BLE Sniffer:

https://www.adafruit.com/product/2269

which uses different firmware than the BLE Friend. You may need to use a JTAG pod instead of trying to do an over-the-air connection. The BLE Sniffer doesn't support OTA at all.

Your best bet would be to contact the folks who wrote the code you want to use and see if they know of any problems using the BLE Friend.

Thanks for answer

I understand Bluefruit LE friend can't be update through OTA .

Explaination are unclear about the way to connect JTAG on Bluefruit LE .

What is the schema between Bluefrit and JTAG ? are we using SWDIO, SWCLOCK GROUD, other Unknown to connect to JTAG . What is the goog JTAG to use ?
