i have a setup with one NRF24L01+ as PTX and one NRF51822 as PRX
my problem is that the data sended ok and ack sended to NRF24L01+(i assume that by NRF_ESB_EVENT_TX_SUCCESS) but NRF24L01+ does not recieve it and MAX_RT ... (more)

recommend me library or a method to setup
Hi. I'm trying to enable and disable softdevice repeatedely. In my code, softdevice is firstly enabled then advertising properly. After some seconds, softdevice is disabled and ESB is enabled. It is worked properly too. and then esb is deisabled ... (more)
I have two nrf51822AC mcu chips that are integrated on custom boards, and I need to communicate between those two chips (one set as a transmitter and the other as the receiver). I wanted to use simple shock-burst protocol but ... (more)
I am using esb dpl in nrf5 sdk v11. I want to put a special packet in ack payload. but I think nrf_esb.c code can not do. the reason is that when on_radio_disabled_rx() is called, tx(ack operation) already ... (more)
Hello , RX: nrf24LU Tx: nrf51822 use ESB Lib. But the nrf24 Can't receive data continuous. if I Want receive 2th data , I must power up the nrf24. This is my Code : RFCTL = 0x10; RFCKEN = 1; RF = 1; EA = 1 ... (more)
Hi ~ I use nrf51-micro-esb on GitHub
In Tx-Device: auto sent (data+1) to Rx-Device
But Rx-Device receiver data still the same not Increment....
why in Rx-Device can't receiver Increment data ??

Hi everyone, Just a brief introduction about my system, I am currently working on Brain computer Interface which was funded by NSF. In our system we have Sense electronics which will provide 10k samples/sec on each of 8 channels ... (more)
Hi,I want to use my phone connect to NRF51822 by BLE, and used NRF24LE1 connect NRF51822 by GAZELL/ESB.That is to say, i want to use the device work with gazell/esb protocol and BLE alternatively! I add ... (more)
I have a custom board with the nRF51822 chip, the chip is set-up with the recommended (CFAC WLCSP schematic with low voltage mode) setup, excluding the external low frequency clock, according to the [nRF51822_PS v3.1].
In this product specification ... (more)
Hi. I'm trying to communicate with legacy nRF24L01P using nrf51822. I received packet from nrf24l01p, but I can't send information back. The data I should send is more than 20bytes, so I cannot use ACK payload. I need ... (more)
I am making some NRF51822-based temperature sensor nodes, powered by CR2032 coin cells, and I would like to minimise power usage in order to maximise battery life. I am using an external TMP102 temperature sensor, transmitting the temperature using enhanced ... (more)
I've successfully used the examples for: 1. OTA DFU for nRF51822 in Bluetooth Smart mode. 2. OTA DFU for nRF24LE01 (2.4 GHz mode only).
But I couldn't find OTA DFU example code for nRF51822 in ... (more)
I'm working on a project where we're having mulitple nRF51822 chips communicate in a multiceiver way. When we bought the nRF51822 chips, the technical sales rep claimed that they could do ESB with up to 256 byte payloads ... (more)
Is it possible to connect nRF905 to nRF51822 via SPI, add ShockBurst code nRF51822 and then use alternately/simultaneously Sub GHz and Bluetooth communication? I'm making an underwater wireless sensor network and 2,4GHz can't go through ... (more)
The device may be talking to a TX/RX station (connected to the Windows PC via USB) that uses an nRF24LU1+ so I'm guessing I will need to use ESB for compatibility. Do I need to load a ...
When running the makefiles found in the esb/gcc_rx and esb/gcc_tx folders I get the following errors:

Does anyone know if ESB example library has LBT implemented?
Been doing a timming mapping between master and slave on packet exchange, and looks like a bit too exact on precise on the receiving and reply times in order ... (more)
The company for which I work is migrating from NRF24 to NRF51. Our protocol relies on ESB and uses payloads of 32 bytes and payloads in ack (also 32 bytes).
With NRF24, the PTX could send (and receive the ... (more)
