    Hi @keencave, I've noticed that backfilling is not working on the Libre Pro, is there something wrong with my set up or is this something that can be implemented? Thanks!
    EricCarbonn
    @Ericcarbonn
    @keencave @daclaw2k I’m not getting any backfilling with the Libre 1 on the latest ino.
    keencave
    @keencave
    @daclaw2k @Ericcarbonn I will test it. It should work. Remark: Only readings which are done with an attached LimiTTter device (but without BLE connection) will be stored and transmitted once a new BLE connection is up.
    EricCarbonn
    @Ericcarbonn
    @keencave Oh... I’m sorry, in that case it’s working fine. Backfilling in my mind was doing the equivalent of the Libre reader that gets the info from the sensor for the last 8 hours.
    keencave
    @keencave
    @Ericcarbonn For the RFduino I support "real" backfilling. I have to port that to Arduino. Maybe in the next release.
    For Libre Pro it would not work as reading the full history buffer it is lasting so long that the battery will drain very fast. We need a a special menu entry in Xdrip+ to initiate that on demand.
    keencave
    @keencave
    @Ericcarbonn Ah, I forgot: Using the native LimiTTer protocol it is impossible do do any backfilling. There is no timestamp for indicating the "time of reading". This only works with the Xbridge2 protocol.
    EricCarbonn
    @Ericcarbonn
    @keencave If I understand right using the Lbridge_Arduino.ino this includes the Xbridge Protocol (and eventually "real" backfilling), but if I set it to be used in Spike, (activating the Limitter protocol) "real" backfilling will never work.
    Marek Macner
    @MarekM60
    Yes, Spike have implemented only current BG without backfill for LimiTter

    thank you @keencave

    Hello,
    Dont suppose anyone knows of any arduino programmable modules that support bluetooth and are tiny, I came across a project that used rfduino but I cant find an rfduino to purchase everything says its discontinued
    keencave
    @keencave
    @c9679 Yes, the RFduino is out of production. You may find some shops where you can get it. I recommend to ask @MarekM60 is he have some remaining Transmiter2 hardware devices. They are RFduino based.
    its not only BLE, but have also WiFi on board....

    @c9679
    Thank you @MarekM60 and @keencave your doing great work and im following Marek Macner progress daily :)

    I did find the TTGO Micro-32 which I thought looked small but I was thinking there might be something smaller than this available lol

    Hello, I'm going to be building the LimiTTer this weekend (hopefully) as soon as the rest of my parts arrive!

    @3ThriftyTrinket_twitter
    I was wondering if anyone had any experience with the Lipo Charger Plus vs the Lipo Charger Basic? I can provide page links if necessary!
    keencave
    @keencave
    Please provide the link.

    @3ThriftyTrinket_twitter
    Marek Macner
    @MarekM60
    @3ThriftyTrinket_twitter for devices like LimiTTer - no important difference between Basic and Plus. In both cases have enough power/current to load small LiPo. Btw. both are "huge" :smile: Such one works very good: -> https://www.banggood.com/TP4056-1A-Lipo-Battery-Charging-Board-Charger-Module-Mini-USB-Interface-p-1027027.html?cur_warehouse=CN

    @3ThriftyTrinket_twitter
    Okay thank you! I was worried it might end up drawing a little more current than the basic but the usb-c connection and minor added protections is super convenient for me. I plan on cutting off the lipo connecter like the instructions say and using the solder points but I'll keep that other one in mind!
    keencave
    @keencave
    Be careful with cutting. Look at the wiretraces in detail before using the saw.
    Arik
    @3ThriftyTrinket_twitter
    Thank you for the heads up, thankfully theres nothing else close to that end other than the solder points I need, I'll still triple check though.

    @c9679
    Just wondering i know its random but what did you guys study etc, Im too old now but I would love to have done some kind of qualification in electronics etc but when I was younger I could never find a course or anything that taught this... I once taught a course myself in PC hardware repair and it was so basic, it was find part broken replace whole thing, one of the exam questions was to literally have the kettle cable unplugged and get the student to tell me why the computer wouldnt turn on and if they could figure out why :(

    @MarekM60
    @c9679 I am 59 y.o. and do not feeling too old.....
    c9679
    @c9679
    @MarekM60 i feel ancient my bones creek im 38 lol, I did software engineering at Uni but always loved electronics and making things :)
    UPetersen
    @UPetersen
    I had no clue of electronics, app programming, Bluetooth etc. when I started all this. I just kept on reading and trying.
    c9679
    @c9679
    @UPetersen ive done that too but still have no idea what cap, resistor, diode etc to put where to make my own circuit... lol wouldnt have a clue how to go about designing something from scratch.
    keencave
    @keencave
    1. Studied physics, no special deep knowledges but familiar with electronics and low level / general C programming. And highly interested in new concepts.
    Marek Macner
    @MarekM60
    My formal is mechanical engeenering - wool and textile machinery design :smile:
    c9679
    @c9679
    @keencave I did Physics at college (A levels UK) didnt do much about electronics though just ohms law etc, @MarekM60 omg lol from wool and textiles to NFC bluetooth micro transmitter design and development :)
    Marek Macner
    @MarekM60
    @c9679 :smile: better - my regular work is design of autopilot systems for small planes :smile:
    c9679
    @c9679
    @MarekM60 so your telling me autopilot systems arent just blow up dolls that fly the plane https://pbs.twimg.com/media/CRXmV7OU8AEuJAZ.jpg
    I think I should have studied mechanical engineering :) darn computer science degrees
    Sandra Keßler

    I write software and doing prototype designs of devices full time
    with a degree in software engineering

    Flunked out of computer repair here so I working production of RFID readers.
    *work in
    c9679
    @c9679
    @SandraK82 how did you go from software to designing devices? We didn't do any part of that in our studies, we learnt programming in various languages however not much on hardware and nothing about components.
    Sandra Keßler
    @SandraK82
    @c9679 I studied software engineering. Not application development. So I got a Good Fundation in engineering concepts. Additionally the it folks where originated from the electrical engineers, math and mechanical engineers. Therefore I had to do many studies in broader engineering and mathematics. Further I was always interested in mechanical stuff. Today I have no real specialization. I use the tools and languages as I need them and technical problems of my customers required me to go deeper into building prototypes. The real devices are constructed by the appropriate engineers, often based on my designs or including ideas I had

    I have a problem with my LimiTTer, I can connect it with xDrip but I dont receive any values. I tested it with an dead L2 sensor and get this in serial monitor, but for me it looks like everything works. Any idea what is wrong?~~~~~.....

    @NFCole
    works again, seems it was a phone problem...
    keencave
    @keencave
    @NFCole Seems that you disabled the USE_DEAD_SENSOR option which is needed to get values from a dead L2 sensor. Logfile said: "no data to send" so LBridge is not sending anything in that case to the xDrip+.
    keencave
    @keencave
    Have to review the code as the S/N in your log is from a Libre 1. Maybe not proper initialiesed for the first loop.

    @3ThriftyTrinket_twitter
    Ugh, just messed up the solder point on my bluetooth module. Any tips for soldering such difficult points?
    keencave
    @keencave
    Use a sharp solder tip. Use Isopropylalcohol to clean the solder pin. Presolder the solder pin before soldering the wire.
    You will find some youtube videos when searching for "xdrip" or "wixel".

    Thank you! Now to wait for another board -_-;
