WL1831: Display BT name in GATT advertisements (only MAC is showing)

Keith Mo

Part Number: WL1831

Hello,

I'm currently using a module based on WL1831 with TIInit_11.8.32.bts, bluez 5.55 and kernel 5.4.142.

I can bring up the BT functionality get hci0 to appear in hciconfig.

I have a gatt server set up and advertising (hciconfig leadv), but on my nRF connect app it is just showing the mac address instead of the hciconfig hci0 name <NAME>.

I'm wondering if there's a lower level command to set the name to be broadcasted?

As a related note, bluetoothctl and btmgmt DO NOT see the hci0 interface/BT device, so I couldn't set the name via btmgmt.

Thank you!

I forgot to mention that the name configured via hciconfig hci0 does show up in the phone's default BT device scanner (scan for nearby BT devices), just the name is not showing up in the gatt browser/app.

Hi Keith, there are no lower level commands for setting the local device name as the one(s) within BlueZ should be sufficient. I'm not familiar with the nRF Connect App, is there something in the settings that can be changed or does a refresh/scan on the app update the device name?

Hi Daniel, thanks for the quick response.

I guess in terms of lower level command I was thinking of how to send mgmt commands when btmgmt does not seem to be detecting the hci0 interface.

I can send HCI commands via hcitool OKAY.

I found Linux/WL1835MOD: kim_probe segmentation fault - Wi-Fi forum - Wi-Fi - TI E2E support forums where it says should no longer use shared transport, so I will try that.

Regarding the mobile app, I have refreshed and also turned BT OFF/ON.

Just updating that after removing shared transport references and loading BT_HCIUART, BT_HCIUART_SERDEV, BT_HCIUART_H4, BT_HCIUART_LL as per Linux/WL1835MOD: kim_probe segmentation fault - Wi-Fi forum - Wi-Fi - TI E2E support forums, I'm able to also set the advertising name and bluetoothctl and btmgmt are able to see hci0.

Thanks!
