Hi @hkn

No it's not enabled. Everything other like GPIO toggling, RF transmit works great...

Have you checked if the nRF24LE1 has the "debug bit" enabled? This can be unchecked in the nRFprobe settings under Keil, or by programming the device from nRFgo Studio and ensuring that "Advanced settings->Enable Hardware debugging" is unchecked before programming.

If the debug bit is set, the core is halted until you send it valid debug commands over JTAG.

Hi @hkn

Tried with hal_w2_write and hal_w2_test_address. On both I don't get any response on the SDA/SCL pin. Tried with resetting and parallel probing on that pins.

Any idea?

Hi,

Are you sure you got the address right? If not it will wait forever in the macro "HAL_W2_WAIT_FOR_INTERRUPT", which expands to:

{while(!SPIF); SPIF = 0; }

If this is where it's stuck, you should be able to see a initial transaction on the I2C bus. Could you try probing the pins, then reset the nRF to see if anything comes out?

Cheers, Håkon
