Possibility to replace directly OPEN LOG ARTEMIS by a DA16200 to send data from a QWIIC sensor ?

Qwiic System
1

I have success with OLA to log data from QWIIC sensor, but I need now to log data from various QWIIC sensors not in the same place. My idea is to connect them through WIFI to a central data log.

But I have not clearly understood if a DA16200 can replace directly or simply the OLA to send data or if I need to add another module and which kind ?

… The simple it would be, the better for me as my capacities to program are limited.

Thank you in advance

This one https://www.sparkfun.com/products/19696 would work as a replacement (we also sell a shield version that would not…it would need an MCU), though it uses a different SDK https://learn.sparkfun.com/tutorials/da … eertos-sdk

You could also take a look at https://www.sparkfun.com/products/15663 which is a bit less expensive - you could even use these https://www.sparkfun.com/products/21293 for a very low-cost solution…though they use BLE, not WiFi

Thank you for your message.

The Nano-beacon seems nice … but in Bluetooth linK.

The story is that, as I have had some difficulties to make work links with Bluetooth (BLE), I concluded that the BLE links could be less robust to pollution.

Q1 : Could you confirm that an external BLE antenna is not needed ?

Anyway, at this price, I could test especially if my targeted Qwiic sensors were in the INPLAY CONFIG Example !

… But this sensor is the SparkFun Triple Axis Magnetometer Breakout - MLX90393 and it does not appear for the moment.

Q2 : But, by chance, you could tell me which other example would be the best to be converted ?

As the foresee network would include 4 BLE individual emitters, each connected to two MLX90393 then …

Q3 : … will the system could send 4 individual full double messages every 10ms ?

Eh, it’d be about the same interference as normal Bluetooth/BLE…fairly spotty, won’t go through many walls/distance

Yes - you would just interface with with over i2c or similar @ default address

That’s a lot of messages…it would really depend on how the program is constructed and the clock speeds available…check the datasheets for max throughputs

Thank you for your message

It seems that it would be too time consuming for me to design and program such network.

So I think I will stay for the moment with internal logging in the 4 items.
