nRF8001 sleep and wakeup implementation?

[gbiradar]

Hi Guys,

I'm working with nRF8001 BLE with PIC18F microcontroller, well i have succesfully completed my project but their one last thing i have to add i.e sleep and wakeup i have followed nRF8001 PRoduct specification and even checked source code. Now my doubt is how do i call sleep and wakeup. As is their any specific API their, if not how do i implement one. i have checked they have declared sleep with code 0x04 and wakeup with 0x05 in aci_cmd_opcode_t.

NOTE: I have to call sleep when my microcontroller is about to go in power saving mode. once microcontroller wakeup i have to wakeup nRF8001.

Please consider fixing the formatting of your question.

To put the chip to sleep call lib_aci_sleep(). To wake it up call lib_aci_wakeup(). Notice that the sleep command is only available in standby mode and that your application controller needs to keep some pins in a defined state as declared in 5.2 pin function in the product specification. Leaving the pins floating will result in the chip staying awake.

Hi run_ar, i don't know how to fix the format. my total project is in c language and call function acil_encode_cmd_sleep(). and acil_encode_cmd_wakeup(). is present can you just check the link and verify it.

One more thing how do i set my nRF8001 in STANDBY mode.

if i set aci_state_t.device_state = ACI_DEVICE_STANDBY;

it is not comipiling and giving error as no identifier in declaration.

I think you are calling the wrong functions. Why don't you use the ACI interface file.
You can force the chip to go to standby mode by calling lib_aci_radio_reset(). This will reset the radio (if you are in a connection it will be lost) and the chip will go to standby mode. If you are in a connection you can use lib_aci_disconnect() to end the connection and go to standby mode.
