Bat detector

Hi,

More often than not this forum post did not arrive in my mailbox, as I am not busy with development I am also not checking regularly.

On Matt's request, the reason for not sharing the 1.71 source has to do with the fact that it has a few unclear problems. If I were to update the code (in coop with Edwin) I would probably start with 1.6 and add possible enhancements on top of that. So 1.6 is the only good stable source.

regards
Cor
 
ive added the 1.71 code for those that want to tinker with the code (see https://codeberg.org/Corbee/teensy_batdetector/releases/download/v1.7/Teensy_BAT_V1_71_20240317.zip)

Be aware that 1.71 has a few problems that have not been solved. They are (as far as I can recall) mainly interfering when using the TeensyBat for autorecording (as a "device") and using deepsleep. The exact nature of these problems never was found and the reports where also not accurate/clear enough.

If anybody "builds" upon this code please share your results so others can enjoy the improvements also.

cheers

Cor,

Thanks for this, I do not think anybody will be critical of any issues in the current baseline - this is an amazing peice of software that works for me almost flawlessly. I am extremly grateful to everyone who worked so hard on thiis hardware and software - it is amazing and I have been using it almost every night.

Question: Do you want to establish a new repository on GitHub or codeberg.com and allow people to create forks and request merges or should we go off on our own? I have been making modifications to the v1.6 code to essentially get it to where 1.7.1 is, so I will abandon those changes but I have also made the change to allow 1.6.1 to support large SDCards.

I would like to modify 1.7.1 with the SDCard changes, but I don't want to go off on my own. If you have an idea for how you would like to control the baseline let me know and we can begin from there. If not, I am open to advice from the community on how we shoud proceed.

Hi Matt,

I am not familiar with the way "forking" works properly and I would like to keep the codebase accessible for all from one location. So ideally it would be good if you could simple share the enhancements on CodeBerg. I am against using Github due to the way open source is slowly getting misused by AI.

If you have a proposal how to "join" forces, feel free to share. You can reach me also via a PM.

cheers

Hi I need some help if possible. I wrongly ordered the GPS. I ordered a Beitan BE-180 instead of a BN-180. I thought that it should work but I constantly get the message GPS not CONNECTED.

Do I still need to do something or is it maybe my connections that are not great?

I know it has tension cause the blue light is working. I am not sure about RX and TX though.

Anyway to test this? Sorry I am completly new to all this.
 
The BE should talk Ublox probably default on 115200. There are some small capacitors over the data lines to try and keep RF noise off these lines, maybe these are to big of a load for this GPS module and baudrate. Try to remove C32 and C33 and try again.
 
Just tried the BE-220 here, seems to connect and disconnect. (Enter the menu and go to the GPS page). I am not sure why, it hink it has a newer Ublox chip than the BN. Current consumption should be less than with the BN but the BN had better reception if I do recall correctly. However it is a bit strange as it now seems to connect and disconnect. I guess you better just get a BN-220 as we know that one works.
 
Alright thank you. If I have budget again I will order the BN-220.
I magically hope it will just start working in the meantime xD.

I'll keep you updated once I got another GPS module.
 
I just placed the BN-220 GPS and it keeps connecting and disconnecting. Is this normal? Or what can I do about it?
 
That is strange, I did see that exact behavour with the BE module. The BE has a version 10 ublox chip, there is some difference in te communication/libraries and M8 or M9 can be used with the libraries used so the BN-220 should work fine. Maybe the it helps to remove the RF suppressor capacitors C32,C33 or lower their value.
