Bluetooth ble support

[sosko71]

Hello, I would like to know if there will ever be support for bluetooth ble. I have an rc Frsky Tandem on which I can only get telemetry via bluetooth ble.

[zs6buj]

Hello, yes there have been a few requests so I will implement BLE. I don't have any commercial BLE adapters to test with, so I shall use the ESP32s for testing.

I will need the SERVICE and CHARACTERISTIC UUIDs to talk to the adapter, or I will need to scan for nearby devices, services and characteristics, which adds complexity and code. But I guess this is unavoidable. It's on my list.

EDIT: The other "little" issue is that the BLE normal message buffer is 20 bytes max, so blocking is needed for messages > 20 bytes. If the commercial adapter implements blocking, I need to know the details. (This should not be an issue for the crsf messages we need for tracking).

[zs6buj]

Can I ask a favour of you? If you have an ESP32 board handy, flash this scan utility onto it, and post the results here. You need to have your Frsky Tandem on at the time.

BLE_scan.zip

Hello I am currently at work and will upload the code to the ESP32 when I get home and paste the results

[sosko71]

OK I managed to get the data. It detected many devices, but my Frsky Tandem is highlighted in bold

This is exactly what I need. Thank you.

@sosko71:

I've added crsfUART2BLE_server and crsfReadBLE_client to https://github.com/zs6buj/CRSF_Utlilties

The server reads crsf telemetry and sends it to the client, which decodes the crsf telemetry and prints it.

There is a wrinkle, as BLE4 sends only displayable text and we want to send a structure containing varying data types that can contain 0x00. BLE4 regards 0x00 as end of message and truncates the full message. So I'm using a COBS (google it) routine to remove zeros and then add them back at the other end. It all works fine this way, but of course we do not know what data your Frsky Tandem sends.

There is also a Generic_BLE_Client.ino in the CRSF_Utilities repo. I'm going to suggest that you change the SERVICE_UUID, the CHARACTERISTIC_01_UUID and the bleServerName, build and flash, and try to connect to your Frsky Tandem. Let's see what it prints.

[sosko71]

Hi Maybe a small problem because I don't use the crsf system. I only have frsky receivers with s-port telemetry

[zs6buj]

Ah, obviously since you have a Frsky Tandem. ok I will have to do a small change for you

[zs6buj]

You can still try the Generic_BLE_Client.

[sosko71]

ok i will test it and post the results

[sosko71]

Here are the data that I get after a successful connection between the esp32 and the rc command, which is connected to the flight controller and receives telemetry

I've updated Generic_BLE_Client to print hex and also text in quotes. Let's try that again so we can see what the telemetry looks like in hex.

Ok, its regular S.Port. Not Fport. I can go ahead and add the BLE to Tracker for Frsky.

[zs6buj]

Which Characteristic UUID did you use?

[zs6buj]

You could try Generic_BLE_Client_Frsky.

[sosko71]

Which Characteristic UUID did you use?

CHARACTERISTIC_01_UUID "0000fff6-0000-1000-8000-00805f9b34fb"

[sosko71]

You could try Generic_BLE_Client_Frsky.

Where can l find it?

[zs6buj]

My bad. It's in CRSF_Utilities now.

[zs6buj]

And which SERVICE_UUID did you use?

[sosko71]

define SERVICE_UUID "0000fff0-0000-1000-8000-00805f9b34fb"

define CHARACTERISTIC_01_UUID "0000fff6-0000-1000-8000-00805f9b34fb"

I have added AntTracker v2.21.08 in the alpha folder. This is VERY preliminary code to support BLE4 for FrSky. Please could you try it with your Frsky Tandem, and past the results when you get the chance. It should print some debugging information for me.

Both are OK because if I try with Generic_BLE_Client_FrSky the connection works. The same values ​​are used in both

[zs6buj]

oops, missed some logic. Could you try v2.21.08b when you can.

[sosko71]

still not connecting

[zs6buj]

Please try v2.21.08b. Tested ok here for connect now.

[sosko71]

I'll test this afternoon as I'm at work right now and post the results later

[sosko71]

The connection is now ok and I get information about the RSSI signal strength on the display, but no information about the voltage and current. Here is part of the data recorded by the serial monitor:

Don't worry about the timeouts at this stage. The serial monitor slows everything way down.

[zs6buj]

I've not been able to get back to tis yet. My apologies. I'll try get get some desk time today and see if I can simulate your data and test like that.

[zs6buj]

I'm seeing some weird app IDs I added some new debug code in v2.21.10b

[zs6buj]

Thank you. The CRC check is failing. A little more progress

[zs6buj]

Ok, I've temporarily disabled the CRC check for FrSky BLE. Can we see what we get now? v2.21.10d

[sosko71]

Ok now a little more telemetry data is visible. I am attaching two txt files, one contains the complete printout of the serial monitor, and the other contains details about the ID codes that I can see in the RC command, if that helps. With GPS coordinates, only Latitude is visible on the display, and Longitude is not visible or read telemetry ID.txt Serial monitor.txt

[zs6buj]

Looking at the telemetry in hex form, it looks like it is periodically corrupted. I looked briefly at the Tandem and Ethos, but know very little about it. Are there telemetry protocol option settings, and BLE settings. Remember BT/BLE use the 2.4GHz band, same as WiFi and all sorts of commercial gadgets. If you are in a room with computers and lots of RF noise this could be a problem. However the corruption seems to be periodic. A latitude of -824.6305542 in not possible, but a latitude of 45.5296783 is plausible. Your first test data, a week or so back, comprised two 11 byte messages combined into a 22 byte block, now I'm seeing zeros in the second block. The esp32 documentation mentions a maximum block size of 20 bytes for BLE4. Have you tried the BLE Scan app on your phone? I saw a 7D 5E pair in there, which could be byte stuffing. I'll look at that tomorrow.

There are no special settings. Only use BLE for telemetry or trainer mode is set.

Yes, I have many different devices, so that possibility is likely

A latitude of -824.6305542 in not possible, but a latitude of 45.5296783 is plausible.

Latitude 45.5296783 is correct, it should extract the longitude from the second number

Your first test data, a week or so back, comprised two 11 byte messages combined into a 22 byte block, now I'm seeing zeros in the second block.

The first data was captured by Generic_BLE_Client_FrSky, while the data captured by Antena tracker only zeros appear in the second block

Have you tried the BLE Scan app on your phone?

I use a BLE scanner with which I also obtained the necessary data for the connection. I also tried connecting the tablet to the RC command and using the telemetry program, which works OK

[zs6buj]

Hmm. Ok, I might have a bug. v2.21.10e. Thanks for the help. My next option is to buy a Tandem lol

This should be better. Updated v2.21.10e to pass object by reference. And tested with fake data.

Still something not ok, getting random reboot serial monitor 2.21.10e .txt

[zs6buj]

I believe this is the clue:

pD len:23

There is an extra byte. We expect 2 x 11 bytes. I think FrSky are byte stuffing the data frame. This is not necessary when an entire frame (record) is transmitted and received at a time, like with BLE. It is used to handle serial framing, when a start/stop character is naturally imbedded in the hex frame data. I hope to look at this deeper later today.

Take a look here

 11 bytes frame started and ended with 0x7E, with byte stuff.  Byte stuffing method: Output Byte in frame has value 0x7E is changed into 2 bytes: 0x7D 0x5E Byte in frame has value 0x7D is changed into 2 bytes: 0x7D 0x5D Input: When byte 0x7D is received, discard this byte, and the next byte is XORed with 0x20;
