WiFi/Bluetooth Demo release

IoT Cards
21

Hi All,
I have layout a custom small formfactor board that includes the TI WL1835 wiFi/BT chip connected dirrectly to a WP8548 processor, using the same connections UART connection and SD signals as the Mangoh platform and WiFI IOT card, Including same GPIO pins for the interrupt lines and BT and WL Enable signals.

There are direct connections with no I2C switches(PCA9548A) in the path, or SDIO switch (TXS0216)
The only other difference as far as I can tell compared to the Mangoh platform is there is no 24C32 1K Eeprom connected.

When trying to initialise the WiFI using wifi client start the first time, it comes back with an error,
and if I try wifi client scan it core dumps.

What would be the best way to manually intialise the TI Wifi driver and print out all the warnings/error messages?

root@swi-mdm9x15:~# ifup wlan0
ERR* failed to write i2c data
FTL* Failed to enable PCA9548A I2C switch

From the Above I suspect that it will be necessary to comment out code that initialises the PCA9548A I2C switch.
May I ask which files I should start to look at to modify in the Source code, and what would be the best way to include back onto the embedded linux platform ?
Is it possible that only the driver may need to be updated, and insmod back in? or is it likely that I shall need to go to the yocto project and recompile the entire environment from the Yocto project?

Hi Asyal,
The new firmware image has yocto built-in. Do I still need to follow the instruction here: https://github.com/mangOH/mangOH/wiki/Bluetooth-WL18xx-driver-for-mangOH to install Bluetooth driver to the mangOH board?

Here is the firmware version:

OK

Here the apps that in my board:

Looking forward your reply and thank you for your help!
Thank you!

Hi YK,

You need to build the Bluetooth drivers and follo instructions as the Bluetooth driver is not built in.

Hi Asyal,
Thanks for your reply. I have encountered issue at step#6ii and iii when I try to change kernel configuration: https://github.com/mangOH/mangOH/wiki/Bluetooth-WL18xx-driver-for-mangOH. Please advise.

Also, the VM I am using to build this image is Ubuntu-16.04. Could you advise what is the “tested distribution” would be best to make this image? What is the hardware spec? By any chance, would that be possible to share the new build CWE images: yocto_wp85.cwe ? We are using the same Bluetooth WL18xx.

Sorry! It should have been -f instead of just f. I have corrected the wiki page. We had a number of issues like this because we migrated some documentation from word into the wiki and it didn’t copy-paste very well.

Thanks for your reply. I actually found this in http://www.yoctoproject.org/docs/1.6.1/kernel-dev/kernel-dev.html as well so I could get Step6 ii worked without error, but still have same error for Step6 iii. Any hints would help, thanks!

@Wavefront_yk I think you should try this from an other terminal, one that support the “-t” option, I’m using terminator and I didn’t have the issue

Option “-t” is no longer supported in this version of gnome-terminal.

Solution:
I have to switch to Linux machine instead of VM with 4 cores, 8GB ram, 50GB disk.
Add “dbus-launch” into line 55 in this file: yocto/poky/meta/lib/oe/terminal.py

class Gnome(XTerminal):
command = ‘dbus-launch gnome-terminal -t “{title}” -x {command}’
priority = 2
