AVR Freaks

Hi.

I have tested both boards as Master , Both produced the 780 Carrier as in the Spec' snapshot.

Now when one configured as slave I don't get the function appDataInd(NWK_DataInd_t *ind) activated ,

This function toggles leds , They do not toggle at all.

Here is the relevant code .

#undef dTransmit

Is there a way to tell if the slave get a the frame or not  ?

Please Advise.

Hi.

Can u be more specific.

I needed to set the frequency to 780Mhz , So the band is 0x04  and channel is 11 .

If u take a close look at the balun it is set for the Chinese WPan 780 Mhz.

According to table 9-34 , base freq 769 + 11 * 1 gives 780 mHz.

Please Advise.

Hi .

I am back . I installed the 2 dc blocking capacitor .

My system two boards:

MCU: ATSAM3S4BA-AU

MCU speed: 64 MHZ

Lightweight Mesh : PHY_AT86RF212 enable

APP_ADDR : 0 –transmit 1 – receive

APP_PANID: 0x4567

Every one second first board (transmit) send message with 32 bytes size and NWK_OPT_ACK_REQUEST, but the second board (receive) not receiving message (not TRX_END flag from IRQ_STATUS_REG in  void PHY_TaskHandler(void))

Notification:

If I set bit AACK_PROM_MODE (Support promiscuous mode ) in register 0x17

So the second board (receive) receive every packet from first board (transmit), but the first board not receiving the ack every packet (one from four or seven)

Please Advise.

Hi.

Spi now is 8MHz .

Problem is the same .

What do u mean by Is your sending side getting a notification? 

Do I get an Interrupt ?.

Please Advise.

Hi,

Setting the delay to 1 ,10,20 uSec , The same problem.

Some test , If the packet length 1s 16 bytes then in Prom mode I get every packet .

If the packet length is 32 and above , I get the packet chopped .

Please Advise.

Hi.

I am using the unmodified code .

I get the packet only when I issue the command

phyWriteRegister(XAH_CTRL_1_REG, 0x02); 

on the slave side.

otherwise I get no packets.

What should be the speed of the micro in order not to use delays  ?.

Please Advise.
