Re: bleprph using HCI 4 wire
Hi Jeff,
It seems you have explicit dependency to net/nimble/transport/ram
somewhere in your configuration (target, I suppose) which you need to
remove. bleprph app already includes net/nimble/transport package
which pulls proper HCI transport package depending on
BLE_HCI_TRANSPORT_* syscfg values and with settings you mentioned in
1st post it will automatically pull net/nimble/transport/uart.
bleuart is not updated to use meta-package for HCI transport so in
order to use it with different HCI transport you will need to manually
remove both net/nimble/controller and net/nimble/transport/ram
packages from its pkg.yml. Also there seem to be some includes from
both of these packages in main.c which are probably not needed and
should be removed as otherwise it won't build.
Best,
Andrzej

Re: bleprph using HCI 4 wire
Hi Jeff,
The `ble_hci_ram_rx_cmd_ll_cb` callback should be getting configured by
the controller at startup (assuming you are running the
combined-host-controller).
I have a few questions:
1. What version of Mynewt are you using?
2. What changes have you made to the apps that are failing?
Also, could you please post your bleprph target? You can display it
with:
newt target show
Thanks,
Chris

The documentation for syscfg settings is in the packages themselves.
Both of the above settings are defined by the
@apache-mynewt-nimble/nimble/transport package. You can see the full list of
settings in a project, along with their descriptions, with this
command:
newt target config show
However, I don't think you will see either of these settings if you execute
this command. From the dependency list you quoted, it looks like you are using
an older version of Mynewt which does not support these two settings. I
believe you are using Mynewt 1.3.0; you will want to upgrade to 1.4.0, released
about one week ago. There was a long delay between the releases of 1.3.0 and
1.4.0, and I mistakenly forgot that 1.4.0 was not yet released when I wrote my
original email.
The latest version introduces some fairly major changes, so I suggest you
upgrade as follows:
1. Download Newt 1.4.0 as described here:
http://mynewt.apache.org/develop/get_started/native_install/index.html
2. Upgrade the Mynewt repos to 1.4.0 by running:
newt upgrade
inside your project directory.
> 2. How can I make sure it's configuring the right UART?
There is a syscfg setting defined by
@apache-mynewt-nimble/nimble/transport/uart called `BLE_HCI_UART_PORT`.
By default, this is defined to be 0. You can change its value if you need to
use a different UART.

I recommend changing the target's syscfg. The target configuration overrides
the app configuration, and it is best not to change a foreign repo except when
necessary. The syscfg system is described in more detail here:

The boot loader is not strictly required, but much of the Mynewt infrastructure
assumes it is present. When you are getting Mynewt up and running for the
first time, I recommend you use the boot loader so that you can follow the
documentation more closely.

I can't find any documentation to what these lines do? The documentation for syscfg settings is in the packages themselves. Both of the above settings are defined by the @apache-mynewt-nimble/nimble/transport package. You can see the full list of settings in a project, along with their descriptions, with this command: newt target config show However, I don't think you will see either of these settings if you execute this command. From the dependency list you quoted, it looks like you are using an older version of Mynewt which does not support these two settings. I believe you are using Mynewt 1.3.0; you will want to upgrade to 1.4.0, released about one week ago. There was a long delay between the releases of 1.3.0 and 1.4.0, and I mistakenly forgot that 1.4.0 was not yet released when I wrote my original email. The latest version introduces some fairly major changes, so I suggest you upgrade as follows: 1. Download Newt 1.4.0 as described here: http://mynewt.apache.org/develop/get_started/native_install/index.html 2. Upgrade the Mynewt repos to 1.4.0 by running: newt upgrade inside your project directory. > 2. How can I make sure it's configuring the right UART? There is a syscfg setting defined by @apache-mynewt-nimble/nimble/transport/uart called `BLE_HCI_UART_PORT`. By default, this is defined to be 0. You can change its value if you need to use a different UART. > 3. Do I change the target syscfg or the one in the app folder? I recommend changing the target's syscfg. The target configuration overrides the app configuration, and it is best not to change a foreign repo except when necessary. The syscfg system is described in more detail here: http://mynewt.apache.org/develop/os/modules/sysinitconfig/sysinitconfig.html > 4. Do I really need the bootloader? If so, is there documentation to why, > I will eventually need to modify this. The boot loader is not strictly required, but much of the Mynewt infrastructure assumes it is present. When you are getting Mynewt up and running for the first time, I recommend you use the boot loader so that you can follow the documentation more closely. Chris
