hi Meng Kai,

Can you help to check the data received from the vendor mode, as well as which PS key does the firmware use for storing store the received data?

I will suggest to implement the test code based on the firmware what your factory are testing.

Thanks

hi Meng Kai,

It's about 1 out of 50 possibility to reproduce the symptom

As mentioned, you can reproduce the symptom with 1 out of 50 devices, and can you reproduce the issue with the specified device reliably then?

I have conducted a similar experiment to store a increasing number to the NVM3 every 1.5s. And about one hour later, it still works well.

Thanks, can you help to check if the data what stored is identical to the data received with vendor model, and you stored these data into the same PS key?

Thanks

hi Meng Kai,

May I know is it easy to reproduce the symptom on your side? 

Regarding to the error code while initialize the mesh node, I suspect it's caused by the wrong information stored in the NVM3. Can you help to dump the flash area and make a comparison between the good and bad node to clarify if any difference between them?

BTW, maybe you can try to simplify the reproducing process by storing some random data to the NVM3 area directly, and perform a power cycle to check if any problem with the node initialization.

Thanks

hi Pat moran,

No, I don't think so you can programmatically set the internal switching voltage. Regarding to the input/output low/high voltage of the gpio pins, please see the datasheet section below. For instance, the min input high voltage is 0.7*IOVDD, which is 2.1v if you power the IOVDD with 3.0v power supply.

hi Leo,

Thanks for the update.

Yes, you can consider to increate the value of SL_BT_CONFIG_BUFFER_SIZE for higher data throughput over connections, advertising or scanning long advertisement data.

hi Josko,

The pin for gpio activation functionality it configured in the "GPIO Activation" plugin, and the GPIO activation plugin is enabled in BGAPI UART DFU Bootloader by default (pls see UG266 for more information). The sequence what you mentioned is reasonable if you've already set the gpio active state as Low.

Regarding to the possible port/pin for USARTx peripheral, please see the table "Table 6.4. DBUS Routing Table" of BGM210P datasheet. Take the USART as example, you can route the USART0.Rx USART0.Tx to any port/pin, however, only PortA and PortB are available for USART1.

hi Tony,

I was wondering how did you do the test, please upload your test project and I'd like to have a review.

hi Yilmaz,

Have you installed the latest Bluetooth SDK successfully, if so, please take a look at section "6 Starting Application Development" of QSG139 for how to new a bluetooth project.

hi Miles,

Please click Help -> Update Software -> Manage Installed packages, and then check the installed Bluetooth SDK, if you are using v3.0.0 SDK, there should be a "Update" button on the right side of the SDK.
