proprietary RF- nRF52840 - first 2 bytes of payload are lost

[Wenne]

Hall Mr. Nordic,

I'm sending a 16bit payload with 51822.

The receiver 24L01 is receiving all perfectly.
The receiver 52840 is loosing the first two bytes ...

nRF51822 tx

Tx payload 16 Bit

'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p'

Rx payload of 24L01

'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p'

Rx payload of 52840

'c','d','e','f','g','h','i','j','k','l','m','n','o','p',0x00,0x00

it seems for me that the payload is shifted two bytes to the right (why? ) -
so how to shift the payload 2 bytes to the left ?

best regards wenne

Hi,

Did you look at the Backward compatibility chapter of the enhanced shockburst userguide? Likely this information will also be applicable for you proprietary protocol.

Could you share the radio registry settings for nRF52840. And maybe also the once you use for nRF51?

Good Morning - it's working now.

I'm reading the m_rx_payload_buffer now instead of

rx_payload.data

best regards
