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.

Normally when we send data via UDP we get a +CEREG: 5 response.
We use this to generate a signal <e_ready which in turn allows the next message to be sent.
(As per the...
