[uldara]

Hi i just bough module nRF52840 from EBYTE.

i test with peripheral work as normal but example Bluetooth Uart not working .  i uploaded success but no device found from my phone.

does module need crystal 32.768khz or not ? because this module don't have crystal 32.768khz

I can't for the love of god make it show in the list of devices. What did I do:

1) Soldered directly to swd/swc/vcc/gnd (I'm using BMP probe).

2) flashed s140_nrf52_6.0.0_softdevice.hex

3) flashed ble_app_hids_keyboard_pca10056_s140.hex

It does not show in the list of bluetooth devces. What did I forget? NRFX_CLOCK_CONFIG_LF_SRC 0 doesn't help.

Yeah sorry I just realized I answered to the offtopic thread, should've been more clear. I'm using nRF52840 from EBYTE, namely CDEBYTE E73-2G4M08S1C. Here's my project https://github.com/joric/nrfmicro
