nRF24LE1 is used in old products. The current throughput rate is 500kbps. I want to increase the throughput rate, but I don't know how to do it.

I just did what you gave this specification. the specification is https://infocenter.nordicsemi.com/topic/sds_s132/SDS/s1xx/ble_data_throughput/ble_data_throughput.html?cp=4_5_2_0_16 . which does not reach 1327.5 kbps, Configuration is as follows:

Protocol	ATT MTU size	LL payload size¹	Connection interval	Method	Maximum data throughput (LE 1M PHY)	Maximum data throughput (LE 2M PHY)
GATT Server	247	251	50 ms	Send Notification	702.8 kbps	1327.5 kbps
				Receive Write command	702.8 kbps	1327.5 kbps

I don't recommend to use the nRF24LE1 for any new development. You can find throughput numbers for the nRF52 running BLE here:

What is the maximum throughput of nRF24LE1?With the nRF52 DK single board, the maximum throughput is 1Mbps, which does not reach 1376.2 kbps. why?

Don't mind the note, this can run on the nRF52832 (nRF52-DK).

The note is misplaced, it should say "This example can also run on nRF52833 with the S140 SoftDevice."

The link says Note: You can run this example on nRF52833 with the S140 SoftDevice. Is nRF52833 with nRF52 DK available?

I want to buy the nRF52 DK single board to test the Maximum throughput。Is there a code example available?

All data transfer in BLE is reliable yes. Data cannot be lost, and data is received in the order they are sent.

Best regards,

For capsule endoscope project, Is Bluetooth communication reliable? I know that the nordic gazella of nRF24LE1 is reliable.

Yes.

Thank you very much. For power consumption and throughput, Is nRF52832 bettor than nRF24LE1?

For new development check out the nRF52832 (or other devices in the nRF52-family):
https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52832.html?cp=3_2

The SDK documentation can be found here:
https://infocenter.nordicsemi.com/topic/struct_sdk/struct/sdk_nrf5_latest.html?cp=5_1

The throughput depends on the configuration of the BLE link, but some numbers are found here (see Table 2 at the bottom):
