Incompatibility between Bluefruit.h and Adafruit_SPIFlash.h

[mulllins42]

Hi all,
First post here after being a stalker for a long time. I’ve been using Xiao NRF52840’s for a long time and am working up a project that requires the 2Mb flash.
I’m seeing an issue trying to output all the data from the flash over bluetooth. It appears to be an incompatibility between the two libraries.
Has anyone successfully managed to connect via bluetooth and download from flash? I’m using non mbed board configs.

[liaifat85]

The error message you’re seeing indicates that there are multiple libraries with the same name, and the Arduino IDE is unsure which one to use. Specifically, the conflict is with Adafruit_SPIFlash.h and Adafruit_TinyUSB.h, where the IDE is using one library version and not the other. You have to remove redundant libraries.

Hi there,

So I believe @msfujino has a thread Storing data in the flash and sending it to a BLE central where it’s stored on SD or something close. Definity look at his technique for that scenario, but fix the conflict first as @liaifat85 points out. review your installed IDE Libraries and fix that. Also FWIW on the Nordic forum there are several posts , Writing the data to flash and then using that as the firmware to boot next… Pretty cool. FYI!
Basically you create a slot in flash that the Update is copied to over BLE and on the next boot is activated.

Thanks so much both, It was indeed the TinyUSB library that wasn’t needed for my use case. I didn’t pickup and was fixated on the libraries that I was actually using! PJ, the self update OWA stuff is really cool and hopefully I can implement something like this moving forward. My next step is for my device BLE to work simultaneously as a peripheral and a controller if possible.

[PJ_Glasso]

Hi there,

Using the Xiao nRF52840 in both Peripheral and Central roles simultaneously is possible because the nRF52840 supports concurrent roles in BLE using its SoftDevice. To achieve this, you’ll need to set up the device with both roles enabled and handle the different connections accordingly.

Here’s how you can approach this:
Check out the Adafruit , example in this thread.it has Dual mode and advertises DFU
change the baud rate to 9600 to make it readable
Check out this thread ;

Seeed Studio XIAO nRF52840 not able to use nordic uart to communicate through app

Hi there, Try this one first. I think it will show you whats wrong. It works perfectly. This code… /********************************************************************* This is an example for our nRF52 based Bluefruit LE modules Pick one up today in the adafruit shop!

I have seen the demos on the NRF_SDK fo rthis working well too, so If you’re using Arduino IDE, consider transitioning to the nRF5 SDK or nRF Connect SDK (with Zephyr). They provide robust support for configuring the nRF52840 as both Peripheral and Central.

• nRF5 SDK: Use SoftDevice S140, which allows the nRF52840 to operate as a Central and Peripheral at the same time.
• nRF Connect SDK: Based on Zephyr RTOS, it has BLE support with multi-role capability.

Using nRF5 SDK

1. Install the nRF5 SDK.
2. Use the ble_app_multilink_central and ble_app_multilink_peripheral examples as references.
3. Merge the examples or use the ble_app_hrs_rscs_relay example, which demonstrates both Central and Peripheral roles.

Using Arduino IDE

The Arduino BLE libraries may have limited support for concurrent roles. You might need to:

1. Use the Adafruit Bluefruit nRF52 library (but verify if dual-role support is sufficient for your needs).
2. Write custom firmware for concurrent Central and Peripheral using the nRF5 SDK.

II was testing with this code also.

P.s I would start a New thread If You need more info in the Dual role scenarios. Tnx.
