propreitary RF send data from 51822 to 52840

[Wenne]

I'm sending Data from nRF51822 to nRF24L01.

The configuration of the nRF51822 is

NRF_RADIO->PREFIX0 = 0x43434343UL;
NRF_RADIO->BASE0   = 0x43434343UL;

The address of the 24L01 is 0x2C2C2C2C2C

This is working perfect.

Now I need to replace the 24L01 by the nRF52840
How to adjust the Address of the nRF5280

uint8_t base_addr_0[4] =  {0x2C, 0x2C, 0x2C, 0x2C};
uint8_t base_addr_1[4] = {0x2C, 0x2C, 0x2C, 0x2C};
uint8_t addr_prefix[8] = {0x2C, 0x2C, 0xC3, 0xC4, 0xC5, 0xC6, 0xC7, 0xC8 };

is not working.

( but maybe there is a problem in my software somewhere else ...)

I tried this also

uint8_t base_addr_0[4] = {0x43, 0x43, 0x43, 0x43};
uint8_t base_addr_1[4] = {0x43, 0x43, 0x43, 0x43};
uint8_t addr_prefix[8] = {0x43, 0x43, 0xC3, 0xC4,0xC5, 0xC6, 0xC7, 0xC8};

it's not working for me ...

Hi,

You can find that we already have an example, source code and description on how to transfer data over the ESB protocol:

https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/examples_esb.html

https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/esb_users_guide.html

In specific check out this info:

Thank you Kenneth,

i already know your links ...

I was asking that you to check the address first, to avoid searching for double faults ... i can search 100 years for my fault if i use the wrong address ...

thank you ...

Hi Kenneth,

I'm able to receive Data from 51822 -> to 52840 now.

But it seems that my Payload is shifted 2 Bytes to the left, that

the

received rx_payload.data[0] holds the data of the send data[2]

received rx_payload.data[1] holds the data of the send data[3]

received rx_payload.data[2] holds the data of the send data[4]

...

received rx_payload.data[14] = 0x00

received rx_payload.date[15] = 0x00

how to shift the rx_payload data 2bytes to the right ?

do I have to use S0 / LENGHTH / S1 for this ?

best regards wenne
