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
Yes, in b112 I am sure!

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.

Nice
You will use the existent softdevice, right ?

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.

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
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! :-)

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
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
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
