About version and SDK question in nRF52810 ， and 2.4G question

[tony55723]

Hi ,

SDK : nRF5_SDK_15.0.0_a53641a

Chip : nFR52810
【1】Is nRF52810 only use pca10040e （nRF52832 = pca10040 , nRF52840 = pca10056） ? And can't use wrong （nRF52810 use pca10040 ）?

【2-1】In examples proprietary_rf , Here is only the example of pca10040 , So I have to download a lower version of the SDK ?

【2-2】This examples ,esb_ptx should be transmitter ,  and esb_prx is  receiver?

【2-3】What is the difference between esb_low_power_ptx  and esb_ptx ? esb_ptx  transmission distance is far?

【2-4】In example file proprietary_rf \ gzll , what is gzll ? Many abbreviations don't know what it is.

（gzp and ack are the same）（Or where is the document detailed ? Instead of every project, go in and see...）

Thank you all, my foundation is not good, but I will study hard.

Hi,

• The SDK only have project files for nRF52810 (pca10040e) in a few examples. However, you can follow the Transferring the project to nRF52810 hardware description to adapt a nRF52840 example.
• You will not find more example projects for nRF52810 in any older SDK, so I strongly recommend that you stick with the latest (currently SDK 15.0.0).
• Yes, the esb_ptx is a transmitter example and the esb_prx is a corresponding receiver example.
• You can refer to the  Low Power Transmitter/Receiver Example documentation for details about the low power transmitter example. Essentially, the receiver is always on so that the transmitter can send data at any time, and sleep the rest of the time (thereby conserving power).
• gzll is Gazelle, which is a Nordic proprietary protocol. It has some similarity with ESB, but is more complex, supporting frequency hopping and pairing. You can refer to the User Guides for details.
