I bought dev board for evaluation purpose (currently run on ESP32)
chip: nrf52832
board:E104-BT5032A-TB (http://www.ebyte.com/en/product-view-news.aspx?id=956)
framework: Arduino
IDE: Platformio
upload: Stlink v2
and tried simple blink to upload w/ STlink v2 in Platformio:
/*
* Blink
* Turns on an LED on for one second,
* then off for one second, repeatedly.
*/
#include <Arduino.h>
void setup()
{
// initialize LED digital pin as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
void loop()
{
// turn the LED on (HIGH is the voltage level)
digitalWrite(LED_BUILTIN, HIGH);
// wait for a second
delay(100);
// turn the LED off by making the voltage LOW
digitalWrite(LED_BUILTIN, LOW);
// wait for a second
delay(100);
}w/ platformio.ini file:
[env:nrf52_dk] platform = nordicnrf52 board = nrf52_dk board_build.variant = generic framework = arduino upload_protocol = stlink
but end w/ error:

nRF52 device has a CTRL-AP dedicated to recover the device from AP lock.
A high level adapter (like a ST-Link) you are currently using cannot access
the CTRL-AP so 'nrf52_recover' command will not work.
Do not enable UICR APPROTECT.

Is anybody can success example?
