  • RE: Intermittent node/gateway radio communication problem

    @genuinejd powering the radio at 5v is way out of spec and will likely kill it.
    I'm not familiar with your pcb, but you could try powering radio+arduino directly from 2 fresh AA batteries, without step converter inbetween.
    These radios are very sensitive to bad power supply.

  • RE: Node not working after adding some wires and a capacitor

    @danielo-rodríguez thanks for posting the photos.

    I see that the nrf24 on your gateway is the variant with the "blob" instead of a chip. If the radio is in a socket, try replacing it with one that has the chip. The clones with the blobs seem to have worse performance, judging by reports here in the forum.

    The antenna on the gateway is pretty close to the metal in the protoboard. Some extra distance could be good, at least to check if the protoboard is messing with the signal.

    Does the gateway nrf have a capacitor to stabilize the power supply?

    https://www.mysensors.org/build/serial_gateway has a sketch for a serial (usb) gateway if you want to build one.

  • RE: Node not working after adding some wires and a capacitor

    @danielo-rodríguez with that much stuff almost touching the antenna, transmission will be very bad.

    There should be at least a few centimetres free area around the antenna. Easiest way to check is to put 1-2 extra headers for the nrf (to get it higher up) or to use dupont wires instead of the header.

  • RE: nRF5 action!

    @monte
    it's not standing against diy'ing etc..really you didn't understand my point, it's just about user friendly and easily repetable getting started for MySensors nrf5 newcomers, for simply flashing their sketch.. even if a diy BMP is certainly a good probe too. and a genuine BMP is more expensive than a jlink mini. Compare both a jlink vs a blank diy probe, and with a stopwatch, you'll see which method is faster and easier for a noob..

    But ok, I won't insist anymore, if you prefer to get me wrong, really don't mind.. I should better let user with not much xp manage all alone so no debate, as this just makes me less active, see you next year 😁

    Just don't forget future newcomers will read your advices. In the meantime, we'll try to update docs for MySensors nrf5.

    Have fun with your probe

    @danielo-rodríguez the new wires, were they added close to the nrf antenna? Could you post a photo of your board. Having anything conductive close to the antenna can have a bad effect on transmission and reception.

    @danielo-rodríguez Supply range for nRF24 according to the datasheet is 1.9 to 3.6V, so you are in the safe range.
    Maybe one of your jumper wires has a bad contact?

  • RE: nRF5 action!

    @monte said in nRF5 action!:

    @scalz well, that's nice that you know what you want and can get it, but that doesn't mean that's suitable for everybody else. That's good to have a choice, but when you need it done, you better find a way to get it done easier and faster.

    Why so much impatience 🙂 So many things to tinker.. I mean you can get a jlink in 2days if you need it. I ordered mine while I was waiting for stuff coming from China..and in my case, there is no close-door store for geeks.
    Do you mean you would suggest a nrf5 newcomer to diy a BMP for mcu flashing??

    When I got my jlink, I didn't have to flash it to make it working.. I just had to donwload win drivers, install them, and voilà.
    Which proprietary sw do you think you need to learn?? I don't use any special sw for flashing..just regular IDEs like arduino/vs studio, or more advanced like Segger (free) or Keil. For all these IDEs, I just click on a button to upload fw, simple. There is nordic windows apps, or nrfjlink in CLI too.

    I know the power of oss and its flaws, same for commercial, in practice it's not rare to see communities sitting/waiting for updates (not hard to find examples on github), whereas money makes commercial products live.
    No need to debate on this, it's useless debate I think
    The reality is different here, I think you'll find more subscriptions-free resources on internet about Jlink than BMP, and for a reason 😉 I agree that you'll find lot of howtos save a few bucks by diy-ing and flashing a BMP..
    everyone acts in one's own interest 🙂
    Just to sum up my thought, I think for a newcomer it's easier to get started with a Jlink vs diy probe that you need to flash with what, a probe ??

    Below is a screenshot of a running nrf5 test, stability test.. but for example you can see, I don't use any additional uart for debug printing, and fw is just uploaded by a click in IDE.

    "BMP is open-source, meaning that you can look inside it if you need or want to"

    "The GDB server is implemented on the probe itself, this means we do not use some proprietary protocol to talk to your debugger software"

    sounds so useful when you simply want to upload fw and debug 😅
    open-source does not mean better quality than proprietary imho, it can be a burden too. I prefer mature product for working.

    is BMP compatible/integrated with as many IDE as a proprietary probe?
    If for instance someday you want to use it with Segger IDE+nordic sdk, is it compatible? I don't think so.
    I "compared" probes recently and decided to stick to jlink. The second probe in my list is cmsis-dap/daplink, looks nice too, but don't need it (at least, not so far)

    I use many different toolchains and CLI too. So when there is a tool that just needs download and exec to install driver, autoupdates etc, without spending life in CLI, I don't hesitate.

    struggling or working..

  • RE: Sketch kills batteries in 2-3 days

    @wahid

    As an example, I have 4 sensebender micros, which has been deployed since june 2015, I have not changed batteries in them yet, and they still report temperature / humidity (that's more than 4 years battery life!). The batteries are cheap AA alkaline types (2 pieces)..

    I'm not doing anything special (hardware wise) to power off the radio, or any other peripherals on the board. Only using standard software powerdown where available.
