OK the problem was the device flashing process, not the BLE adapter itself. For a reason, the J-Flash Lite tool did not flash the NRF52 the first time.
After some tests, both my CSR and Broadcom based BLE dongles are working fine :-)

The Nordic 'Thingy' has been renamed jpthingy.
Yes I flashed the espruino_1v92.111_nrf52832.hex firmware via a J-LINK debugger, but I wonder if I should have flashed the ZIP archive instead of the .hexonly... ?!?

Hi guys.
I have a case where my device is visible but I do not have any web bluetooth button appearing in the Native IDE. Here is the console output:

The device is a Nordic "Thingy" based on NRF52. I don't use Puck.js because I temporarily lost it . . .

I tried with both CSR and Broadcom based BLE dongles, same result. In both cases the IDE finds the device but when I select a port, no Bluetooth port appears. Check box Connect over Bluetooth Smart (BTLE) via 'noble' is checked. Espruino Native IDE version is win64_0v65.9. Any idea?

That would be a nice to have indeed! I will keep this idea in mind for later.

@Gordon I know that unofficial boards may not benefit from any support, but I ask the question anyway (it might also be helpful for Puck.js users): Is there a way of flashing the .hexover OTA or do we absolutely need to give it a .zip archive? nightly builds for the NRP52 kit seems to be .hexonly...

Any support planned for the Nordic Thingy dev kit? https://www.nordicsemi.com/eng/Products/Nordic-Thingy-52

It runs on nRF52832.

Often the I2C master [here, the stm32] is strong enough to force a line to 0V through a 4k7 resistor. I bet the problem here is the RTC itself which should probably have weak output drivers unable to push the lines to zero Volts (thus, very low current drained which is a good point for a RTC in term of power consumption).

I2C is an addressed bus. This means you can have multiple slaves communicating with (usaually) a single master. Often, different kind of I2C devices have different addresses. Your I2C lcd is not likely to have the same address as your Chirp.
The difficulty comes with multiples devices of same kind, such as two or more Chirps. In some way you have to differentiate them on the I2C bus. Fortunately, Chirp seems to provide a way of doing it: https://github.com/Miceuz/i2c-moisture-sensor/blob/master/README.md#address-change-example

I never tried. Please share your thoughts on this method if you try it! :-)

@furuskog if you have access to I2C on the puck, you probably will succeed in integrating this chirp sensor.
I2C1.setup({scl:B6,sda:B7}); You just have to change the name of SCL and SDA lines and it should just work.

Also, why would someone choose the Espruino WiFi when they are connecting via LoRa? "If you're using this breakout board then you can place it in breadboard alongside an Espruino Pico or WiFi, making sure it connects as follows..."

LoRa and WiFi are totally different. With LoRa you will achieve very low power consumption. With WiFi you will benefit from relatively high bandwidth. As always, it depends on what you want to do :-)

I wrote a guide for that a few months ago. It is not totally completed but you should still be able to make your first experiments by following it:
https://github.com/yerpj/TTN_with_Espruino/blob/master/QuickStart.md

sorry, not anymore^^

on my browser (Firefox ) the font is very small on the API referencepage

Improve LED color blending: Replace 3 discrete R, G, B LEDs with a composite RGB LED. Probably save board space, too.

I am using Rohm SMLP34RGB2W3 for a long time. very bright, very small, a few cents in quantity.

Thank you !

Yes I'll be using the Pico.
I'll have a look at the doc concerning this 128kB page.
I may try to implement DMA functions in the near future. If anyone reading this message already played with the DMA in Espruino, I would appreciate to get any feedback :-)

It is possible to set up DMA directly from JavaScript

By using peek/poke, or by another mean?

I also think that the DMA should be a helful peripheral for that.
With the current version of Espruino, what would you suggest for storing raw data stream in flash?

I would say as fast as possible :-)
I wondered if I could output a stream at, let's say, fclk/2 or 42MHz ....

Hello guys!
I would like to stream on a digital output at a given rate from a large file or array.
I know the waveform class but it is dedicated to analog data. What is the best way to replicate the behaviour but for binary data?

Thanks for your feedback

Enjoy your deserved vacation!
Thank you for the huge amount of work behind Puck.js and Espruino. I hope 2017 will be another great year for the community

FYI:
I had almost the same issue. I completely uninstalled the BTLE dongle (ASUS BT400, based on the BCM20702AO chip) and reinstalled using standard Windows 7 drivers (+automatic online driver update). Now, the dongle is well recognized by the Espruino "native" IDE and I can scan for Pucks around.

ooooh that's totally true. I ever forget to give it the callback :-/ sorry for wasting your time with such beginners issues...

@Gordon I tried the method getStatus() of the module RN2483 (LoRa)

Talking about promises, I just got this error message:
Uncaught Error: Unhandled promise rejection: Error: Function "b" not found!
Does it means that we absolutely need at anytime to give both resolve AND reject callbacks?
Is it possible that it worked with 1v87.XXX but not anymore with 1v88 ?

great!

@DrAzzy from my own experience, for such a device it will be far better to use a dipole antenna. The one pointed by Gordon should be a good candidate.
