Not uploaded with mbed

Development Platforms
#1

I build and upload my mbed program using PlatformIO with VSCode.
I seemed no errors as follows.

But It looks BLE Nano doesn’t run new program.
What the matter ?

Have you verified that this is the correct drive?

If it hangs up during runtime we’d need to know what program you’re running. Does a simple blink sketch? A “hello world” via serial?

#3

Thank u for your replying.

Yes, I tryied to build and upload the example “mbed-blink” (https://github.com/platformio/platform-nordicnrf51/tree/master/examples/mbed-blink)
But the result is same.

I found that there isn’t exist file “.pioenvs\redBearLabBLENano\firmware.hex”.
This is right stauts?

#4

Meaning what result? No LED blinking? Can you check the PlatformIO core version used? (pio --version or the version string in the VSCode GUI)

Yes, No LED blinking.

Can you check the PlatformIO core version used? ( pio --version or the version string in the VSCode GUI)

I use this PlatformIO core.

PlatformIO core: 3.6.4

#6

Are you sure you have the right board? Is it a RedBearLab BLE Nano 1.5 (nRF51 chip) or RedBearLab BLE Nano 2 (nRF52 chip)?

#7

Yes, I use BLE Nano 1.5.
I checked the board print.

#8

Can you check if it works with the Arduino IDE? (- YouTube)

#9

Actually the problem does seem to be as you noticed

This was reported here: nrf51822 : support for mbed framework broken · Issue #26 · platformio/platform-nordicnrf51 · GitHub

Can you try to go to your platformio.ini and roll-back the used framework version? Put

platform = nordicnrf51@4.0.0

(or @3.5.0 if this doesn’t work) for the environment you’re using.

#10

I already use nordicnrf51@4.0.0.
So I tried with nordicnrf51@3.5.0.
Then uploading succeeded !
Thank you!

#11

Then uploading succeeded.
… But LED stil not blinking

#12

What code are you using? If you follow the LED1 definition what pin does it refer to? Is that the correct one for your board?

I use the following “mbed-blink” (https://github.com/platformio/platform-nordicnrf51/tree/master/examples/mbed-blink)
And use pin “LED1”.
I confirm the code is right by building with mbed.
