Pins soldered together RCP2??

[nymand94]

I am having trouble getting my telemetry working on a Racecapture Pro MK2 with a GSM module. (I believe it is the 2.5G type, can anyone confirm?)

The RCP2 board has 2 pins soldered together going to the GSM module, can anyone confirm whether or not they are supposed to be soldered together?

I have attached pictures of both the GSM module and the soldered pins.

Those should not be soldered together. Can you try unsoldering it?

Is this the first time trying to use it? What cell carrier are you attempting to use?

I have unsoldered the pins, and tried to setup the whole thing from scratch. I have updated the firmware and followed the telemtry guide.

I am using a danish operator called telmore, with a 3GB/month data-plan, which i believe shold be more than enough for 2 weekends of sprint racing per month. I have called the carrier and had them confirm that they are still live on 2G network, so this should not be the problem either.

I have pulled the log on the RCP2, and had the following:

Correct me if im wrong, but i believe there should be an IMEI number in the last part of the log: ""cell":{"init":0,"IMEI":"","sig_str":0,"number":"","state":"unknown"}", which there is not. Cold the soldered pins have fried the GSM chip?

It is the first time i am trying to use it, the RCP2 was mounted in a racecar that i bought secondhand. i dont know if the previouse owner have had any luck using the telemetry.

In your log file I don't see any messages about attempting to communicate with the cellular module.

Try ensuring that the cellular module is turned on under Setup / Wireless, then, write, then power cycle the system.

You should see additional messages in the log after that.

Also, what firmware is the system currently at? The firmware is shown in the upper right of the app after it connects.

I was running 2.16.0, i just notice that 2.17.0 was released yesterday, so i updated. now i am running 2.17.0 and I am getting this Applicatoin Log:

I tried pulling an Info log under scripting and got this:

There are alot of CAN errors, i don't have CAN connected at the moment, i dont believe this should effect the telemetry?

I have ensured that the cellular module os activated under Setup -> Wireless -> Cellular.
I have the correct APN acoruding to my cellular provider. I have Bluetooth and WiFi disabled to ensure they do not interfere with the GSM connection. i have disconnected the GPS antenna to make sure it doesn't interfere the the GSM antenna.

Under Setup -> Telemetry, I have background streaming enabled, and the correct Device ID

I have attached a picture of the window: System status - Cellular, which indaicated the cellular module has not been initialized.

Hi,

For the RaceCapture log you have enabled "debug" mode. Set the log level to "Info" and you won't see the CAN messages.

The RaceCapture application log is not useful for this, so you don't need to include it.

Thanks.

Sorry for the late response but this was not a very high priority during the season and early-off season.

I do now have the time needed to find out why this is not working.

I have updated the firmware to the lates version 2.17.4.

I have pulled an info log with the following:

Code: Select all

Logging stopped

Logging started

[fileWriter] Start

[fileWriter] Opening log file

[fileWriter] Opened rc_26.log

timebase/logging/telemetry sample rate: 50/25/25

timebase/logging/telemetry sample rate: 50/25/10

I don't believe anything is wrong in this log.

the racecapture app states the cellular module as not being initiallized, i have attached a screenshot.

I have enabled cellular ind the setup, and also enabled telemetry, sceenshots attached

In the menu preferences, The "Send telemetry" is enaled, i don't know if this should be on or off?

Hi - the settings under App Preferences turns on broadcasting telemetry through the app - see the note under the setting.

If you don't have built-in cellular in RCP (or you don't want to use it) - you can turn this on.

If you're trying to use RCP's built-in cellular, you must turn this off.

Which way are you wanting to do this?

It's good to review the overall setup guide for real-time telemetry, here:
https://wiki.autosportlabs.com/RaceCapt ... _telemetry

[nymand94]

I want to use the build-in 2.5g cellular module

I Will turn off the teleletry through app and der og IT changes anything.

I have read the teleletry guide, so i know it requires 12v in the green terminal, and i am giving it about 5 minutter to initialize.

[nymand94]

I have tried turning off app telemetry - now the info log looks different:

Code: Select all

[Conn task] not connected. retrying
[gsm] powering off cellular module
[gsm] power off response: false
[cell] Power cycling modem
[cell] Resetting modem...

Could this be an antenna problem? since it is apparently having trouble connecting.

I have this antenna installed: https://www.delock.de/produkte/G_88571/ ... anguage=en

I know it says LTE antenna, but it should work with GSM aswell.

I have tried mounting the simcard in my phone, and it had full coverage, also when i turned off 4G and 3G in my phoes setting.

[brentp]

Does your RCP have the cellular option installed? The key indicator would be if it has a SIM card slot on the front panel.

[nymand94]

Yes it does. and it is with the Sim900 chip, which i suppose is 2.5G GSM network?

[brentp]

The SIM900 is a 2.5G module, correct. if you are in the USA, the only carrier that will support it is T-Mobile, FYI.

With the SIM900 module, you also need to power it with 12v - it cannot be powered just with USB power. Try providing it with 12v and watch the log file while it tries to connect.

I am in Denmark, Europe.
I am powering the rcp2 with direct 12v through the green terminal. So this should not be an issue.
I have confirmation from my carrier that they are still love on the GSM -network
