How to Reset nRf 8001

[Saurabh Gulia]

I have a custom PCB and i have connected the MISO,MOSI,SCK,REQN and RDYN line from the nRF 8001 to Arduino. And uploaded your code of ble_uart_project.ino but nRF 8001 does not started advertising. When i debugged closely i came to know that nRF 8001 does not get reset as i am not getting any event from lib_aci_event_get() function. Sometimes i got error printed on Serial Monitor and i.e "Error in Setup" . I even tried Projects given by Red Bear Labs with their libraries, but still not able to get any event from nRF 8001 and it clearly means that nRF 8001 is not getting Reset.Because as soon as it get Reset i will get an event ACI_EVT_DEVICE_STARTED, but i am not getting this evt.

The custom PCB and the connection are absolutely right and i am powering nRF 8001 from 3.3V supply only.In the above setup i have not connected Reset pin from nRF 8001 to anu pin on Arduino? Do i need to connect this? Can you provide the code snippet which actually Resets the nRF 8001. I had even tried resetting through soft reset with the help of this function lib_aci_radio_reset() but again the same issue?

Help me over this!!

Try connecting the reset pin and use lib_aci_pin_reset to reset the chip. I would recommend downloading our latest arduino sdk from github: github.com/.../releases

lib_aci_radio_reset does not reset the chip, only the radio, ref the product specification.

Which Arduino pin should i use to connect Reset line of Olimex Module. And this is the code of of your function:

if (UNUSED != a_pins_local_ptr->reset_pin) { pinMode(a_pins_local_ptr->reset_pin, OUTPUT);

if ((REDBEARLAB_SHIELD_V1_1 == a_pins_local_ptr->board_name) || (REDBEARLAB_SHIELD_V2012_07 == a_pins_local_ptr->board_name)) { //The reset for the Redbearlab v1.1 and v2012.07 boards are inverted and has a Power On Reset //circuit that takes about 100ms to trigger the reset digitalWrite(a_pins_local_ptr->reset_pin, 1); delay(100); digitalWrite(a_pins_local_ptr->reset_pin, 0); } else { digitalWrite(a_pins_local_ptr->reset_pin, 1); digitalWrite(a_pins_local_ptr->reset_pin, 0); digitalWrite(a_pins_local_ptr->reset_pin, 1); } }

Well this time i am not using Red Bear Shield but i think this will work only for them. I have my own custom pcb which i have bought it from https://www.olimex.com/Products/Modules/RF/MOD-nRF8001/ . Will this work for my module also what should i use in board_name? Should i use REDBEARLAB_SHIELD_V1_1 as board_name?
