Basic UART over BLE?

[la-ble]

I'm trying to enable basic commands with my device. Ideally I have a terminal open on a mac running nodejs or use the UART subapp in the nRF Toolbox App, type a special command character then press transfer.

There are a handful of apps in the examples that have uart somewhere in the name, but none of them seem to be able to simply abstract a put_char and on_char_received...as far as I've found. That's really all I'm looking for: Push a character out to the Tx buffer and then get an interrupt on a character received.

I'm tested with examples:

• ble_app_hrs_s110_uart_pca10028
• ble_app_hrs_s110_uart_stm_pca10028
• ble_app_hts_s110_uart_pca10028
• ble_app_proximity_s110_uart_pca10028
• ble_app_uart_s110_pca10028

All the ROM and RAM settings under Options for Target -> Target are immediately wrong and it just gave me qualms about using this as a learning point in general. I did however get something from ble_app_uart_s110_pca10028.

What is the most relevant example to consider when using the S110 soft device and working with a PCA10028 dev board? What is the simplest way for me to integrate the simple firmware API of put_char and on_char_received into my own firmware project?

Hi la-ble,

I am not sure if I understand what you mean by abstract put_char and on_char_received. Are you saying that you do not need to forward BLE traffic to/from UART? Or are you asking if you can use NUS service and also abstract put_char and on_char_received functions in addition to NUS?

I will help you and edit my answer after I understand what you are really looking for

@Aryan, I do NOT care about the UART hardware peripheral. I only care about sending/receiving debug data over BLE to/from an iOS device. 'Emulated' UART might be a better description I could have put down.
