    yes sure. For example, in Mysensors, I have now 4x nrf52 nodes (aeos and other custom boards) talking to esp32+nrf24 gw.

    So, NRF52 <-> NRF52 and NRF52 <-> NRF24 are working well, and you can simply use Mysensors examples and set the defines, that's all, nothing more to do, it's transparent. Thx to the Mysensors NRF52 ESB port, pretty cool.

    For bluetooth, I've started to take a look for a simple BLE phone app too, for fun. That said with BLE available, we could get nice features in Mysensors..

    Finally, little sidenote about my simple range tests. They were quick, not in ideal conditions, but gave me an indication.
    I have tested BLE and Mysensors modes. Power supply for the node was 2x fresh AAA battery:

    • as a BLE beacon, and was checking the rssi with a phone app. Not a precise test as rssi is not linear.
    • with Mysensors. A simple counter was sent to the gw and i was looking for missing packet.

    I'll do more tests of course because some variables can change the results (like if it is in enclosure depending of wire antenna or not, orientation ..). For example, I will check pcb antennas by testing communication between two identical nodes.

      @scalz Have you checked if there is a difference in range between NRF5_1MBPS and NRF5_BLE_1MBPS data rate?

        @scalz 👍 Thumbs up for a 2450! You have it on your other sensor and I'm using it for PIR is makes sense. 2032 is fine for a long sleeping sensor, but PIR will drain it very quickly.

          @d00616 no. that was just a quick test during euphoria :blush: but that's an interesting point i need to add on my ToTest :+1:

            Congratulations. Very nice concept. But I understand nothing about the range. Is it comparable with nrf24 or is it by a decade more? :)

              thx. I'm not sure about what you don't understand :)
              If you're wondering about nrf24 vs nrf52 range, i've not tested this, i'll do that as soon as i get my custom antenna version of the board.
              Because comparing a nrf24 module with pcb antenna Vs nrf52 with a chip antenna or an untuned wire antenna isn't a valid test, I think.

                @scalz OK, waiting your results. For now I've just found some information about tx power:
                nrf24: nominal - 0dbm, max - +4dbm
                nrf51: nominal - 4dbm, max - +6dbm
                Not very high power :(

                  @scalz have you seen this module ?
                  PCB antenna + IPEX, and with 52832 we're sure it's not a clone...
                  At this price I can directly dump my atsamds and nrf modules :o

                    It's very nice that they offer up the info needed to create the land pattern. That info seems absent from quite a number of the aliexpress modules.

                      @Koresh
                      Yes, still an interesting improvement :) And i have powerful multirf boards too so..
                      Well i think you know it, but range is not so easy to compare, that depends on a lot of factors like datarate, ant, enclosure etc..

                      @Nca78
                      yep, saw it too. I don't think they're selling clones, they looks nice ;)
                      Module is too big regarding my board and all what's embedded. I also wanted a stronger antenna.
                      This kind of meandered antenna, often the same for wire antenna though, may be prone to some detuning (regarding enclosure, environment etc.) and loosing some efficiency etc. So maybe not the full range, can be a lot less, depends (100m for this module in datasheet).

                      But yes i agree with you :) 328p too limited, obsolete imho, "end" of nrf24 lol, and atsam is nice depending on the usecase. Personal view of course!

                        But I think I'm still about to make one last 328 board to make a really small and low power sensor.

                        Would you share eagle and schematic files for your prototype with the module ? I have ordered modules from EByte and I'd like some inspiration to prepare a first test board :D

                          Thanks for posting that. I just now ordered some. However, they may not arrive until September! Yowza. That means their shipping container is practically a time capsule.

                                    @NeverDie hmm.. guys could you open a new topic regarding your nrf52 module please?
                                    (as i'm not planning to use it for Aeos, cost almost the same for me to use the IC, and i can do more compact stuff)
                                    Else that will be a mess here ;) Thx!

                                    @Nca78 will upload some sch, was busy..

                                    Here a very simple rfm69 extension for Aeos, when i need more range:
                                    0_1499848156858_Aeos with rfm69.png

                                    And a simple pcb for quick reprogramming the first time (as the next times it will be through OTA).

                                      OTA ? Is a bootloader already made ? :o

                                        There are some stuff already existing though.
                                        You can take a look at Adafruit nrf52 board, they have a bootloader for BLE, and their sch can also help you to understand how the above module is working in case.
                                        Regarding Mysensors OTA etc, stay tuned..

                                          It would be nice if you can enable OTA. The DFU bootloader is placed at the top of Flash. This region conflicts with the NVM driver. You have to move the used Flash region.

                                          The bootloader is documented at http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v13.1.0/lib_bootloader_modules.html

                                          At the moment I have no time to work on an bootloader. If you want to discuss things you can contact me.
