I have repeated all step and see same as you have described. I can scan BT devices, but ‘D-Bus setup failed’

thank you!

Hi @mango, It looks like the R11 WP77 Linux still has some drivers/tools missing which are needed by bluez. I’ve not tried the customizing the Yocto/Linux approach yet. Looking at different threads, the mangOH yellow with WP77 should have all the tools integrated with it.

26

in other words, it means that in fact mangOH Red with WP7702 and WL18 IoT does not have Bluetooth capability, right?

27

in fact android BLE scanner can see mangOH BLE endpoint and mangOH can see android, but ‘connect’ fails on both sides :frowning:

Do you have a WP76? If you do, you can try the recently release WP76 R13 FW(https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-latest-release/) which includes all the BT tools by default. I was able to use R13 out of the box using red-bt-init.sh (707 Bytes) and pair with a Ti Sensor Tag.

The next WP77 FW release should also include all the tools by default for BT.

29

no we do not have WP76 :frowning: but what is major difference between WP77 and WP76 ?
Can it be that WP76 firmware will work on WP77 (at least bluetooth part) ?

30

when it is planned? we have limited timeframe and should provide solution to customer with WP7702 and BT.
Would linux.cwe from WP76 release work on WP7702 ? or may be somebody could port changes from WP76 linux branch to WP77 to get it fast?
thank you

31

The WP76’s FW cannot be used with WP77 as they are 2 different modem families. WP76s are CAT1/CAT4 and WP77s are CAT-M/NB/2G. You can refer the spec sheets for the modems at https://source.sierrawireless.com/.
I don’t know the release dates for the next WP77 firmware but it should be available in next couple of months or so.

32

will it be correct to say that ‘bluetooth’ officially not supported on WP7702 until next firmware release ?

33

What’s your use case? Are you planning to discover other sensors ?

34

our application exchange data with smartphone over BLE and with SIM using APDU commands, no other sensors used
