BC127 is connected with phone, but phone doesn't display BC127 properly

Hello,

I have an issue connecting with my phone after certain conditions are met, that I feel shouldn’t affect the phone. Here is the steps I take after I have done my restore/write/reset to flush the BC127 settings and unpaired on my phone and unpaired on the BC127.

I see the device on my phone, so I tap the device on my phone to pair. The response I see is:

OPEN_OK 14 BLE 5D11DB2E1135
PAIR_PENDING
PAIR_OK 84119E71A98C
BLE_PAIR_OK 5D11DB2E1135 84119E71A98C
CLOSE_OK 14 BLE 5D11DB2E1135

So, the device is connected now. I now activate AVRCP, A2DP, HFP.

open 84119E71A98C a2dp
PENDING
OPEN_OK 10 A2DP 84119E71A98C
ROLE_OK 84119E71A98C M
OPEN_OK 11 AVRCP 84119E71A98C
AVRCP_PAUSE 11
AVRCP_STOP 11
OPEN_OK 13 HFP 84119E71A98C
ROLE_OK 84119E71A98C M

This is fine too. But, on my phone I see two BC127 devices:

And then after I tap the arrow on the top left and navigate back to this setting, I see zero devices:

This makes it look like I’ve got no device connected, though my Bluetooth symbol on the phone shows that I’m connected to a Bluetooth media source and that I can stream media to that source.

Note: there is absolutely no issue playing music or making phone calls. The only issue is only the display in the phone’s Bluetooth settings for the device.

Previously, the blue BC-088DFA would move up to the “paired devices” on my phone and change its name to BC088DFA (short name) and still the BC-088DFA black name stayed with the paired devices list without ever moving. I still didn’t like this previous set up where it shows two BC127 devices, but now, I see nothing.

How do I get it so I get to see the BC127 device on my phone? Is this an issue with the BC127 itself, or is it with my phone?
Thanks,
Steven.

Steven,

Not too clear what the issue is here, can you send the below commands to the device after it has been paired with your phone and you see the ‘problem’.

What is confusing it a bit is the fact that at the beginning you are sending ‘advertising on’ which is a BLE command where you seem to just want to operate using Bluetooth classic (A2DP, HFP, AVRCP, etc), if your device is discoverable (BT classic) and advertising (BLE) then the phone will see it as two devices, however, once the unit is BTC paired with your phone by default it will stop itself being discoverable.

Again by default the BTC name is with the dash, the BLE one without.

Matt,

Thank you for the quick response. The module responds perfectly fine if I don’t set this ‘advertising on’ command.

Having two BTC, BLE devices at once makes perfect sense to explain what’s happening.

For anyone that finds this in the future and wants to know what was done, look at the BL_STATE command or BL_STATE_CONFIG configuration. I seemed to have missed this command and configuration entirely.

For completion’s sake in case someone wants to know what I have:
