Hi,
I'm interfacing a nrf51822 and a H8/3294. My question is how much can I drain a the txd pin of the H8/3294. That means my question isn't really about nrf51822.
In documentation...
Hi,
On the 3.30 of nRF52832_Rev_1_Errata_v1.5.pdf, the sleep current with LFXO active is 0.5μA higher.
I am using a nRF52832 module with the low frequency crystal oscillator...
Hi,
I'm using nRF52832 on SDK V12.2. I add the connection params in the conn_params_init:
static void conn_params_init(void){
uint32_t err_code;

I want to use whitelist function in this example but I can't finish it.
When I run peer_list_get(), it gets all 0xFF, means that...
I'm just reading the documentation regarding the analog digital converter and wonder why there is one bit in the configuration register for every analog input. What will happen...
I'm using a relatively large GATT db that has rd_auth and wr_auth set to true for every characteristic. This prevents the stack from automatically replying with cached values...
I'm using the MAX9814 electret pre-amp's output as an input to an analog pin of the nRF51822. The MAX9814 has a 1.2V swing at 1.2V DC (so it goes from 0 to 2.4V). VDD for...
Hello,
I have some questions about the DC/DC conversion factor in nRF51822.
In the datasheet nRF51822_PS v3.1, Figure 11 shows the graph about conversion factor...
I would like to change the device name of the nRF51422 trough a mobile device(Android AND iOS ). The name should be stored even when I disconnect the supply.
From a nordic...
Sir,
We designed a prototype card including "rfd22301" containing nrf51822. We will use in mass production directly the nrf51822.
We will use the BT as a transparent UART...
