How to setup BCSP at runtime with manufacture specific commands #bt #protocol #hc5 #bcsp
I like to implement an firmware upgrade via bcsp + manufacture specific commands. I give a quick setup of my system:
BT device <---> UART3 @ MCU <---> Zephyr OS
The update process works in following steps:
- open uart3 9600,N,8
- send "DFU"
- open uart3 115200,E,8
- establish a link via bcsp
- sending and receiving the manufacturer specific commands on
Now comes my question: How to do this with Zephyr OS?
I saw a implementation of the HC5 protocol:
Think I may can use this, because it is said, that the bcsp can
be used in combination with HCI HC5. Am I right?
The dfu commands using channel 12 of the bcsp. For me seems that function "static int h5_queue(struct net_buf *buf)" is only handling cmd/event and acl messages. How to it is dealt with all the other ones? ( acl = 6, cmdEvt = 5, sco = 7, le = 1, ack = 0, dfu = 12)
