Respected SIR,
We procured nrf8002 BLE for our product. Currently we are in developing stage. We are using arm coertex M4-32bit based Teensy3.2 board as master. We havent bought Nordic developing board. We chose to procure QFN32 package breakout board. We did smd soldering of nrf8002 ic over breakout PCB board successfully. We did multimeter continuity check. No shorting errors found over any pin. As for the inintial stage we tried to power up BLE with 3.3V. We followed schematics available in Datasheet. We also referred development kit hardware document for more details.
After providing all peripheral connection, BLE is undiscoverable in Nordic Master Control android application. From nrfgostudio 64 bit (windows) its communicating somewhat in Direct Test Mode. On starting transmit test, Tx indicating LED of FTDI cable is blinking, but since BLE is undiscoverable in Nordic Android application, we are unable cross check BLE bluetooth transmission.
While uploading configuration settings from nrfgostudio, UART Rx fail error occurring. We cross checked UART connections which were fine.
Can you guide us in this issues. Does BLE ICs from Nordic comes with inbuilt bootloader/firmware or we have to flash them manually.
I have attached our schematic of our peripheral connections over nrf8002, which is based on datasheet schematics & Development kit hardware document.
Note: Here, inductors with range of mH are unavailable. Hence, we replaced the inductors (range of nH) from documents schematics with inductors of 1 microHenry value as this are least valued inductors available here.
