How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hi.
I'm doing a project of wireless sensor network. It is a small network of less than 6 elements, so I'll use piconet. I have ble_app_hrs working perfectly. But only with...
Hello,
I'm working with a nrf51822, SoftDevice S120 v2.0 and SDK v9.0 platform.
Specifically using it a Central role to connect to a Blood Pressure peripheral.
When...
In section 7.5.2 of the nRF24L01 Datasheet it states:
PTX enters RX mode and waits a time period for an ACK packet each time a packet is transmitted.
During this...
Not really a question, but I found a potential issue with the Battery Service module in ble_bas_battery_level_update() . This is in both SDK v10 and SDK v12.
The problem...
Up to this, we've been prototyping with MDBT40 module in our prototypes. We want to move to a completely custom PCB using the nRF51822 SoC for a number of reasons (space and...
Hi,
I am using nRF51-DK with softdevice S130 and SDK 12.0. I am working on the BLE central role with ble_nus_c service. I am able to setup the multiple connection with...
Hello,
In the last month i bought the nr52-dk, my first two steps handling it were:
the getting started tutorial and some other tutorials to get the feeling of the...
I am doing some test with the Battery Service on SDK v10, and found out that if I have not enabled Notification on my phone, calling ble_bas_battery_level_update() returns...
Hello.
For routing purpose, I use GPIO pin for NFC for spi, driving a screen.
I start a screen integration with the with the spi peripheral example projet. Using the define...
I am using the nRF52 (SDK12.0.0) to create a very simple BLE application (maybe based on the BLE_APP_HRS example). The system will have a button, LED and interrupt pin from...
Hello,
we have successfully run Nordic chip together with iPhone and we are able to get notifications from iPhone to the embedded device using ANCS via Bluetooth LE.
