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...
when I add my own service and add characteristic, a odd phenomenon confuse me.
When I set cccd_md.write_perm:
BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cccd_md.write_perm);

after several attempts to debug and understand what goes in my handlers in the BLE callbacks, I thought to give a UART logger a try.
this is what I'm trying to use: OpenLog...
Hello,
I am looking for a not expensive way to program nRF51822 by frame of 10 modules. All the 10 modules would be connected to a PC using pogo pins, and I would use a...
