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...
Hello,
am I right to assume that if sd_ble_gattc_write returns anything other than SUCCESS, then the packet was not queued?
Is this also true for BLE_GATTC_EVT_WRITE_RSP...
Hey guys,
I have a little problem on a new board comunicating with a MPU9250 sensor.
Chip version is nrf52832-QFAA-BA

The S332 v0.6 has been released and it is supposed to be compatible with SDK11. My concern is that in the release notes of SDK 11, it says "Temporarily removed support for...
I tried the above example but it hangs here:
while (ser_sd_transport_is_busy());
Not sure why, I'm using GDB to step thru code, and it appears always busy...
Is there...
Device: NRF51-DK
I'm using GDB+OpenOCD to step thru code and it appears that the nrf51 resets itself after calling:
SVCALL(SD_BLE_GAP_ADV_START, uint32_t, sd_ble_gap_adv_start...
I want to make rs485 communication with nRF51822. I gone through the UART code, there CTS , RTS pin are required , but for my case tx, rx,rx enable is enough, and also shall...
Hi everybody!!!
I am making a project which use NUS service and I have confuses in connection mode:

Hello, my question is pretty clear i guess. Is it possible to schedule advertising of 2 different packets on the same chip ?
The way i see it, it should be possible to...
Good morning, I´m trying the example of this post (ble_app_template_with_pstorage_operations_nRF51DK.zip). I have SDK 8.1.0, softdevice 110 and nrf51-dk.
The source works...
Is there any clear documentation to add an external memory to the nrf51822 to store some sensor data. How is the performance and stability when interfaced this way?
Dear all,
I'm working with nrf52832 and SDK 11.0.0.0.
I want to upload SD 2.0.0-7. Download results OK but,
