Reset signal of nRF8001

[masahiro-yoshikawa]

Hello.

I use BLE Shield V.2.1 of RedBearLab.com for Arduino. The shield equipped nRF8001.

After about 62ms from reset nRF8001 by putting Low signal in Arduino pin 4 (set it on a reset pin), at first main board (NUCLEO-L053R8) recieve "0x00 0x82 0x40 0x01". And next, after about 510ms from avobe signal, main board recieve "0x01 0x04 0x81 0x02 0x00 0x02"(maybe "DeviceStartedEvent").

Is this behavior right?

I assume that it may be right to recieve "DeviceStartedEvent" first after reset.

You need to verify that your SPI configuration is indeed OK, by using the ACI Test command and the Echo command. The Device Started Event is ok after a reset but you are seeming getting it twice, and the first one appears to be malformed (62ms) and then you get a second one at 510ms

I would also suspect the the nRF8001 is getting reset a second time either due to a power supply glitch so I would verify that there is enough power for the nRF8001.

Take a look at the porting guide for more input.

Apologies for the delay and assume that you were able to overcome this issue.
