a problem in "ACI_DEVICE_STANDBY"

Mohsen

hi. Im working with nrf8001 type c in a self-designed board and im using arduino library driver on github by nordic. my mcu is stm32 and i ported library to my mcu. when I debug my program i find that my program go to "ACI_DEVICE_STANDBY" case in aci loop and nrf respond me with "03 84 0F" . as i understand, it means that nrf will advertise in this state. but when i use a smartphone with android 4.4 and BLE enabled i cant see nrf8001 in nrf uart app that made by nordic in play store. and im using service.h in "hello world" project.(type c , internal 32768, external crystal 16 MHz). please help what problems may be exist im my project or what points I have to check again? thank you.

    thank you for response. As you said I can't see my nrf8001 advertisement in 1 cm distance from smartphone even. I use 32KHz Internal RC (in fact i didnt use any 32KHz external component or clock source) and 16 MHz external crystal.

    you can see my frames that sent via uart for debuging from starting program.(note that my uart frames are always 8 bytes) I have a question. why in some cases nrf8001 send me 03 as len but I receive 4 bytes. for example 03 84 06 01 02 ??? is it a fault?

    • Run the ACI transport verification.

    • Look at Section 7 in the nRF8001 Datasheet which explains the position of the debug byte.

    • Get an nRF8001 D version as that is the latest version with a number of bug fixes, you will save yourself a lot of pain.

    • The length bytes are to strictly used i.e. any data beyond the length should be discarded.

    • You receive the "03 84 06 02" (see the Section on the setup command in section 24.6) followed by a Device Started Event (04 81 03 00 02) so the nRF8001 seems to have started successfully.

    • The Connect command seems to have been successfully sent but there is no Disconnected Event after that.

    • Your UART trace is not easy to understand, how are we to see the order of the ACI Events. Attach a trace that has shows the order of the messages.

    Thank you David for your response.

    *I ran ACI transport verification. Its OK. ("Echo OK")

    *my received packets respectively are:

    04 81 02 00 02 _ 03 84 06 01 (for many times) _ 03 84 06 02 _ 04 81 03 00 02 (for 2 times) _ 03 84 0F 00 (forever)

    What timeout and adv interval values do you use when issuing the connect command?
