BLE Micro (v1.2) I am not able to solve this issue

I have bought a BLE Micro.

  1. I downloaded “nRF Connect App for Android” on the phone.
  2. I downloaded Arduino Library “https://github.com/sandeepmistry/arduino-nRF5” and also “RedBearLab/nRF51822-Arduino”
  3. I open Arduino Blink sketch, selecting board “Generic nRF51822” or “redBearLab nRF51822”.
  4. I generate .Hex file, send to the phone, and I am able to upload as “application” with the nRF connect App. It also asks for a .dat file, but it can upload th .hex file even if it is missing (how should I create it?)
  5. Application is downloaded, 100%.

But nothing happens! I tried both nrf_gpio_pin_set(xx) and clear, and also digitalWrite, but no way any of the pins shows any sign of life. I tried with multimeter, they stay about 300mV fixed. Also with an led connected both to vcc - or gnd, and the pins. Nothing. What am I doing wrong?
Also the pinout is not 100% clear, I looked at https://infocenter.nordicsemi.com/pdf/nRF51822_PS_v3.1.pdf and tried pin 3, 30, 25,26,29, … always no results.
Any help would be greatly appreciated.

This is a very old Seeed product.At present, it is a software update, and the documentation is not updated timely

I bought it after seeing this post, is 8 months “very old” for a product?


Is it replaced by a newer product in the same size, with Arduino support?
Thanks

https://github.com/sandeepmistry/arduino-nRF Support for BLE Micro is also very simple. You can use it by adding the pin definition of BLE Micro to the rest of the board.
