We haven't seen this issue on a devkit before. Which OS(Windows, Mac OSX, Linux,etc) are you using on your computer?

yes we use nRF52-DK(PCA10040)

Do you have an explanation ?

It seems that changing the MTU_SIZE fixed the issue. From 250 (initial code example) to 23.

class IMU_Collector(BLEDriverObserver, BLEAdapterObserver):
def __init__(self, adapter):
super(IMU_Collector, self).__init__()
self.adapter = adapter
self.conn_q = Queue()
self.adapter.observer_register(self)
self.adapter.driver.observer_register(self)
self.adapter.default_mtu = 23

Another Service with a lowest ODR don't failed.

Something not normal I assumed.

Hi,

Do you use a nRF52-DK(PCA10040) or a custom kit?

It seems that this is an issue reported in the Library:

H5 Decode packet size is not good.

if (slipPayload.size() != calculatedPayloadSize)
{
return NRF_ERROR_SD_RPC_H5_TRANSPORT_SLIP_CALCULATED_PAYLOAD_SIZE;
}
