Anna-b112 Bluetooth module support
Hello Nuttx Community,
First i would like to say that i really hope that everybody is doing well!
I am sorry that long time i didn't had a chance to contribute anything, but
life is moving in a very fast pace for me lately.
For our sport Wearable system i am working on integration of a Bluetooth
module Anna-B112, it is a very interesting small module. The version which
we are using is preflashed with Ublox u-connect software and the module is
based on nRF52832 nordic chip. I would like to ask for advice on how
exactly to implement a relevant support for this to suit Nuttx architecture
because i wish to contribute this port when its done. I am familiar that
Nuttx has Bluetooth stack and also support for HCI bluetooth modules, but
the difference here is that ANNA-B112 has its stack embedder in the nordic
chip and the module is controlled via AT commands through UART, so i am not
exactly sure how to implement the driver for this module. To me it looks
like it has to bypass the nuttx bluetooth stack (because it already has an
embedded one) and directly connect to the application layer, please correct
me if i am wrong here.
I would really appreciate some insight of how exactly to implement the port
to suit Nuttx design and to NOT disrupt in any way the already existing
implementations of bluetooth connectivity
Thank you in advance!

Posted by Tim Hardisty <ti...@jti.uk.com.INVALID>.
With apologies for joining in - at only a slight tangent I hope - but is the advantage to a NuttX app that uses the NuttX Bluetooth stack with the radio device in H4 API mode, compared to using the Bluetooth SoC device as a coprocessor using its own stack, that it becomes a simple device that can be read/written to rather than needing a custom SPI or USART interface protocol to be written?
I have a similar situation to Ivan in that I have a board with a SiLabs Bluetooth LE SoC and I have assumed I'd use it's stack and SiLabs tools to create my Bluetooth LE App, and have it communicate with my "main" app via an SPI interface in some custom (not yet designed) way - but perhaps I'm missing out on something easier by doing it that way?

Hi Ivan,
Right, I think this is a good approach case you don't want to replace
the firmware.
Maybe for WiFi the u-connect could be used with USRSOCK.

Thank you Alan for you time, really appreciate your advices and
recommendations,
Hello Miguel,
Indirectly yes,as far as i know ublox use softdevice in their u-connect
firmware, but not 100 % sure about that.

Re: Anna-b112 Bluetooth module support
Posted by Embedded Systems <iv...@gmail.com>.
Hi Alan,
Unfortunately ublox does not, maybe Nordic does, but i dont wish to reflash
the module. What i am thinking is to implement an u-connect parser similar
to the NMEA parser (GPS parcer) and implement it in utils in apps, in this
way i wont disturb the already existing Bluetooth functionality and add
support for ublox devices which use u-connect, they have also Wifi and
other modules which use u-connect so i think it will be nice addition to
have this parser in Nuttx.
Best regards,
Ivan

Hi Ivan,
Ok, understood the issue!
Maybe U-Block has an HCI H4 firmware that you can use on Anna-B112
instead of this AT firmware. It's always a good idea to use and follow
the standard, this is a compelling motivation to use NuttX in the
first place! :-)

Re: Anna-b112 Bluetooth module support
Posted by Embedded Systems <iv...@gmail.com>.
Hello Alan,
Unfortunately we cannot use the module as HCI H4, we can control it only
with AT commands. So in our case IMXRT is running nuttx and its connected
to the BLE module with uart and control it with AT commands, so far i just
implemented an application in nuttx which controls the module from the user
space. The aplication is using a UART char driver to communicate with the
module and everything else is managed in the application , but i dont think
this is a good way to use the module and i wish to make a driver in nuttx
for it, My problem is that i dont see a good way to implement the driver
and connect it with the already existing nuttx Bluetooth functionalities .
Best regards,
Ivan

Hi Ivan,
Normally using external BLE modules that follows the HCI H4 is easier
than porting to some chip with internal BLE and application in the
same chip.
You can see how it is done in the sim and also here:

Hello Alan,
Its good to hear from you too.
So, you don't to flash NuttX inside Anna-B112, but just want to use it
as external BT BLE module, right?
The Anna module is flashed with u-blox connect and we are using it as
external ble module, the module has the whole ble stack embedded in the
u-box connect and is controlled via AT commands, thats why i am not sure
how exactly to port it for Nuttx in a suitable way.
Best regars,

Re: Anna-b112 Bluetooth module support

Hi Ivan,
Nice to hear news from you!
So, you don't to flash NuttX inside Anna-B112, but just want to use it
as external BT BLE module, right?
In this case you need to enable the "Bluetooth H4 UART"
There are some examples on NuttX about how to use it.
Also you can opt for using NuttX internal BLE Stack (that derives from
an old BLE Stack that Intel integrated on Zephyr and that was released
for Arduino/Genuino under BSD License) or you can use the NimBLE stack
that is more complete and also have examples on NuttX.
Using the internal stack could be more challenging, but it will help
to improve our own stack.
BR,
Alan
