Can’t program BT832 Module using NRF52-DK

I have read articles on the forum, watch youtube but still no luck. Actually I failed to find step by step tutorial how to do it from start to the end. Most of them touch wiring stuff only.

Hardware:

Wire thing up, just like devzone.nordicsemi.com/.../ or devzone.nordicsemi.com/.../ (tried both, with external 3.3v power for the BT832 module and w/o)

Try to flash:

Using any ble peripheral example from SDK:

  • Cd pca10040/s132/armgcc
  • Make, make flash_softdevice, make flash

Using NRFog Studio:

  • See only 2 regions. No matter power I BT832 externally or no.
  • Re-flash both softdevice and application with appropriate binaries.

Both actions successfully flash NRF52-DK only, but the BT832 left blank. How I check - I try to discover BLE devices using phone (nRF Connect application). NRF52-DK - fine, but BT832 invisible.

What am I doing wrong? Wiring schema I found in many places and it seems fine. Maybe I should programm is some other way and specify some extra attributes to point external device, not just NRF52-DK?

  • You need to connect the P20 GND DETECT to the Gnd on your custom board, and if you use PCA10040 to power up your custom board, then yes, the Gnd on your custom board becomes the GND (say from P1) of your PCA10040.
