Again: Bluetooth Not working kernel 4.4.16-v7 #36

I saw this was closed under #13 but it seems to be broken again (and kernel was updated 2 weeks agao). Bluetooth option is shown but if you try enable , it won't enable.

Is there any method to downgrade the kernel version, so we can use the BT in RPI android 7 or 6?

I'm too having problem with bluetooth, even in the rtandroid image the bluetooth is not working anymore.

If I try to enable it, after some time it gets enabled, but soon after start using it, the bluetooth dies.

I saw the following message in logcat:

01-01 00:06:00.767 1118 1147 I bt_core_module: module_start_up Starting module "controller_module" 01-01 00:06:01.410 1118 1137 E bt_hci : command_timed_out hci layer timeout waiting for response to a command. opcode: 0xc03

Here is a log: bluetooth.txt

Can verify bluetooth is not working on RTAndroid 7.1_r4 with the latest kernel 4.4.23.

@danielcbit Seems to be fixed now in RTAndroid.

I solved this problem.

File -> /hardware/broadcom/libbt/src/hardware.c line -> about 235

static const fw_settlement_entry_t fw_settlement_table[] = { {"BCM43241", 200}, {"BCM43341", 100}, {"BCM43430A1", 1000}, // <- add this line {(const char *) NULL, 100} // Giving the generic fw settlement delay setting. };

After I add above line and rebuild system.img, Bluetooth worked.

Sounds great, maybe @peyo-hd could integrate this change in the main repository?
