nrF52 and serial example, Connection failed: no serial service

[bossesand]

I use the serial example, have only changed the BLE_pins to pins not used on the Taida Centurty nrF52

I can see the BLE device in the Android Serial Bluetooth Terminal app but cannot connect I get the error Connection failed: no serial service I loaded the S132 to the board first then I flash the app using ST-Link V2

Using Android app UART LE
Serial service found Did not find any GATT characteristics - when trying to connect

Any pointers on how to proceed?

@bossesand do you have a link to the Android Serial Bluetooth Terminal app? Is it intended to be used with the Nordic UART profile?

Hi Here is the BLE nordic UART Apps links that works with adafruit but not with your example. I have a Taide Century mini devkit

https://play.google.com/store/apps/details?id=com.nordicsemi.nrfUARTv2 https://play.google.com/store/apps/details?id=com.cmd.blechat

BUT I have not succeded in getting the example to work...

But as I have downloaded the Arduino support for this board I get the Examples for the feater uart to work, I can send bleuart strings https://www.adafruit.com/product/3406

BUT a LARGE BUT, I cannot get the Wire example to read a adafruit bno055 module over i2c/TWI and send any sensible data over bleuart.

I have a salea 8 logic analyzer, and I cannot get see any sensible data reads on the i2c bus, I can see just a lot of NAC accesses. I saw one time data as it should look but I cannot repeat that.

So I hope you can improve your example so that I can get bleuart connectivity, I think/hope your Wire implementation is better....

Hi again I feel so stupid... I cannot understand what is going on. I am modifying a sketch to test the wire implementation with reading a bno055 module. I have am using a sketch that I had tried to get to work with BLEPeriferal, I have removed all references / calls to BLEPeriferal. Why is the BLEperiferal library still used ? at this moment it might not be a problem as when I remembered to specify the softdevice S132 the sketch compiled OK... But it would be interesting to know.

Can anyone explain how libraries are handle in the arduino windows version? any link to a description /user/bosse/Appdata/... Documents/arduino/library and libraries in the sketch folder

I get so tired of my lacking understanding of this :-( I recieved a Adafruit nrf52 feather today https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/examples I tried to lightly modify the uart example... ' I want to read a bno055 over i2c and print out quaternion data like this, a 2 as first char for CmdMessenger message type strings 2,0.644,-0.762,-0.012,-0.067; 2,0.644,-0.762,-0.012,-0.067; without this: !!!

I had for a while ble uart connectivity working even if the data was coming over as one character per line!

When trying to do adhoc stuff to fix that, I lost ble uart connectivity... so now i do not get uart connectivity to the Android app UART-LE

I just want to run a generic nrf52832 module, read quaternion data from a bno055 over i2c and send it over a BLE NUS uart connection to a lot of different master devices Windows OSX IOS and Android

So a Simple working example to start again with :-)
