Iphone bluetooth issue

[Bitbanger1900]

Hi,

I see on 2023.12.07 Added TTGO Lilygo LoRa32 v2.1 board as Bluetooth TNC(Android/Apple) and as a Tracker (with external GPS module).

I tried multiple Iphones with this TTGO but i don't see the Bluetooth Lora device. On Android Phones it is working without problem. Do i have to set a different Bluetooth type in the config?

Regards, Johannes.

Hi

Apple works different:

You can't add a BLE unit on the BT part of preferences/configuration of the iPhone.

It only works when adding inside an app.

So for now it's working inside APRS.fi app when adding as a TNC

Hi,

Thanks for your quick response! That is actually exactly what i did. Opened aprs.fi, go to TNC & DPS Modem, selelect a TNC or software modem and than it keeps on searching but it finds nothing.

There are a few things to test:

Reset or close APRS.fi app Turn off and on BT on iPhone Turn off and on tracker

Hi,

Tried all those but not working.

When i set bluetoothType to 0 in the tracker_config.json and call BLE_Utils::setup(); in the void setup(); i do see the BLE TNC discovered?

[richonguzman]

you should see the TNC to add it (but first, do you have the TNC and messages capability in aprs.fi )??

[Bitbanger1900]

Hi,

Yes. i have the TNC and message capability in aprs.fi.

I added in the LoRa_APRS_Tracker.cpp file above the line WiFi.mode(WIFI_OFF); the line BLE_Utils::setup(); so that the BLE_Utils routine is always executed.

After that all is almost working fine except one thing. When i open a console i see that the message what is passed to the gateway over Lora is cutting of the SSID. So i see my callsign and not callsign-14 passed to the iGate on the Tracker on the serial console.

1) maybe is an issue of filesystem upload as "BluetoothType":0 would force the BLE to work without any issues

2) explain me more about the callsign problem please: Where do you have the missing ssid? On the serial output? On the trackers? On the phone?

[Bitbanger1900]

1: i'm going to test.

2: within aprs.fi i configured my Station as OE2XZY-14.

I connect the tracker to a serial output and have the following output. As you can see on the last line it says: OE2XYZ> and i believe it should be OE2XYZ-14>

[richonguzman]

What is the SSID in the aprs.fi app?

[Bitbanger1900]

OE2XYZ-14

[richonguzman]

Could not find any station with this callsign on aprs.fi to see raw packets

[Bitbanger1900]

correct. i changed it of course as i will not publish my callsign/GPS in public on github

[richonguzman]

Write me a telegram message at my github user to know your callsign and look at raw packets to help you further

[richonguzman]

please download the latest "main" firmware and update as it should be corrected now
