Programming off the shelf CSR8635 module – Page 1

I recently bought a cheapie Bluetooth -> Stereo amplifier board. It works pretty well for what I need and I’m thinking about buying another. Unfortunately the device comes with “SANWU Audio” as the hard-coded BT device name. I’d like to change that to something nicer like “JamBox”, especially if I’m going to have two of these sweetpeas.

Has anyone had experience with re/programming these modules?

My stereo amplifier had this soldered on to it: http://www.dx.com/p/csr8635-2-channel-bluetooth-v4-0-module-black-blue-368089

Possible pinout for module: http://g04.s.alicdn.com/kf/HTB1Med2FVXXXXaIXFXXq6xXFXXXJ/220226238/HTB1Med2FVXXXXaIXFXXq6xXFXXXJ.jpg

I’m starting to think the “Debug SPI” on the chip (PDF: http://www.csr.com/sites/default/files/csr8635_qfn_technical_overview.pdf) isn’t exposed on the outside pins…

how to assign static IP on a switch – 14861 – The Cisco Learning Network

Engineering and technology notes

Jovan Stosic June 14, 2017

As you may know there are layer 2 and layer 3 switches. A layer 2 switch only does layer 2 fowarding, as such it doesn’t have any additional ip interfaces. On a layer 2 switch the ip address is instead assigned to the vlan interface:

config t

interface vlan 1

ip address 192.168.1.1 255.255.255.0

* Note on a L2 switch you can assign an ip to any vlan you want (vlan 1, vlan 2, vlan 4000). You can only assign an ip address to one vlan at a time on a l2 switch. If you configured an ip on a vlan and then try to assign an ip to another vlan…the switch will shut down the first vlan and bring up the second vlan interface)*

On a L3 switch you can have multiple ip interfances. Unlike a L2 switch, an L3 switch can have static ip addresses on multiple vlan interfaces (configuration is the same as the above example). In addtion unlike L2 swithes a L3 switch can have a static ip address assigned to any one of its fastethernet (fa0/1) or gig ethernet ports (gi0/1).

Config t

int fa0/1

ip address 192.168.1.1 255.255.255.0

description *** Assigning an ip address to a physical fast ethernet port on the switch***

int vlan 1

ip address 192.168.2.1 255.255.255.0

description *** Assigning an ip address to the virtual (vlan) interface on the switch ***

int vlan 2

ip address 192.168.3.1 255.255.255.0

description *** Assigning an ip address to another virtual (vlan) interface on the switch ***

Note that although you can assign multiple ip addresses on a L3 switche’s physical (e.g. fa0/1 fa0/2 gi0/1) or virtual (vlan 1, vlan 3, vlan 3000, or a loopback lo1, lo2,lo3), all of the ip address must be in different networks. If subnetting is used, the interfaces belonging to the same switch must have a different subnet mask.

Example

int fa0/1

ip address 192.168.1.1 255.255.255.252

description *** This interface is on the 192.168.1.0/30 network ***

int fa0/2

ip address 192.168.1.5 255.255.255.252

description *** This interface is on the 192.168.1.4/30 network***

int vlan 1

ip address 192.168.9 255.255.255.252

description *** This interface is on the 192.168.1.8/30 network ***
