Bluetooth (LE) on MangOH Red with IOT Card


#1

Hi,

I want to use Bluetooth on MangOH Red (WP7702) with the IOT expansion board (Mirage). I’m struggling a bit with scattered informations on forum, github, documentation, …

So far, I compiled and integrated the bluetooth layer (https://github.com/dpfrey/yocto_wp76_wp77_meta-bluetooth):

root@swi-mdm9x28-wp:~# lsmod
Not tainted
bnep 13788 0 - Live 0xbf0aa000
hidp 15938 0 - Live 0xbf0a2000
rfcomm 56860 0 - Live 0xbf08c000
hci_uart 43635 0 - Live 0xbf07b000
bluetooth 389826 6 bnep,hidp,rfcomm,hci_uart, Live 0xbf000000

I compiled and integrated BluetoothUtil and BleSensorInterface but BluetoothUtil returns me some errors about the mux command (which seems related to the mangOH Green, am I wrong ?)

I therefore bypassed this command and run “hciattach /dev/ttyHS0 texas 115200 flow” but it returns “Initialization timed out.”

Am I missing something ? Any help would be really appreciated :slight_smile:
