Receive uart data from different MCU and advertising this data

[sasci]

I try to onewire communication for DHT11 but I couldn't it . I decided uart instead of onewire. The different microprocessor will read the sensor data and send it via uart. NRF52840 will receive and advertising data over uart. How do I to do this? Is there a similar example?

Hello

You could have a look at any peripheral BLE example to see how advertising is done, for example this one.

In order to update the data you're advertising you can use the bt_le_adv_update_data function documented here.

Hello

Thank you for answer. I'm already advertising the battery but I want to read multichannel adc with it

And I've another one question. I've also review similar issues on this platform and read that Uart and Ble beacon don't work together. Can I find a solution for this?

Since you're using an nRF52 device, you can use the UARTE peripherals with EasyDMA support, allowing you to receive data directly to RAM while the CPU is busy with BLE operation.

Thank you for help I will try it.
