Arduino Hardware supporting WiFi and BLE in a single sketch

Projects General Guidance

Hello,

I am new to the Arduino World and even newer to this forum. I am seeking advise regarding the subject of this "topic".

Background:

For a few weeks, I have been trying to employ a MKR 1010 WiFi to build a system, which basically collects data from a BLE sensor to post it to a proprietary cloud-service via http.

I only just found out that the MKR 1010 WiFi cannot handle this, because it is unable to provide WiFI and
BLE functionality simultaneously (i.e. within the same sketch). - This was just confirmed to me by the official Arduino support (i.e. Mr. Joyal John).

It would be great, if some of the more experienced Arduino users could provide some advise with respect to any alternative hardware (preferably Arduino compatible) that can be employed for the given task.

I would like to stay away from solutions involving a Linux operated Raspberry Pi or something similar,
since the application requires very robust instant-on and instant-off capabilities.

Any suggestions are greatly appreciated!

Who told you that a Linux device isn't able to provide this?

I'd suggest an ESP32. It provides support for the requested functionality, at least as far as you specified it.

Thank you for your response.

Pulling the plug on a Unix system is usually not a good idea, e.g. since they typically, use RAM with swap-disks.

Thank you very much, I had looked into this, it seems, though, as if people have been reporting problems,
e.g. WIFI/BLE Simultaneously - ESP32 Forum, Can ESP32 parallell processes the Bluetooth and Wi-Fi? · Issue #1196 · espressif/esp-idf · GitHub, and more ...

Then again, Espressif's ESP32 FAQ (chapter 5.3.1) seems to indicate that it is indeed possible after all.

Have you tried it yourself ? - If so, have you been using the Arduino IDE or the ESP-IDF ?

No. I used only the BLE functionality of the ESP32.

It's not easy because they share the same radio hardware and both are using the same frequency range.

It seems you never used an embedded Linux system. You shouldn't pull the plug (better all plugs) of a big Linux server but did you have problems when you lately pulled the plug of your Internet router? There a 99.9% probability that it runs Linux. My heating system also runs Linux, your phone most probably runs a flavor of Unix as well as most devices that have more or less smart interfaces.

BTW, do you know what a swap disk is? Using RAM with swap disks never was the problem with power on Unix machines...
